All right, since I bombarded a poor mutual yesterday...
Privacy is not security and security is not privacy. These terms are not interchangeable, but they are intrinsically linked.
While we're at this, anonymity =/= security either. For example, Tor provides the former, but not necessarily the latter, hence using Https is always essential.
It is impossible to have privacy without security, but you can have security without privacy.
A case in point is administrators being able to view any data they want due to their full-access rights to a system. That being said, there are ethics and policies that usually prevent such behavior.
Some general tips:
Operating System: Switch to Linux. Ubuntu and Linux Mint are widely used for a reason. Fedora too. And don't worry! You can keep your current operating system, apps and data. If you're on a Mac computer, you can easily partition your hard drive or SSD by using Disk Utility. If you're on Windows, you can follow this guide.
You want to go a step further? Go with Whonix or Tails. They're Linux distributions as well, but they're both aiming for security, not beauty so the interface might not be ideal for everyone. Many political activists and journalists use them.
You want anonymity? Then you need to familiarize yourself with Tor. Also, Tor and HTTPS and Tor’s weaknesses. When you're using it, don't log in to sites like Google, Facebook, Twitter etc. and make sure to stay away from Java and Javascript, because those things make you traceable.
Alternatives for dealing with censorship? i2p and Freenet.
Is ^ too much? Welp. All right. Let's see. The first step is to degoogle.
Switch to a user-friendly browser like Firefox (or better yet LibreWolf), Brave or Vivaldi. There are plenty of hardened browsers, but they can be overwhelming for a beginner.
Get an ad blocker like Ublock Origin.
Search Engine? StartPage or Duckduckgo. SearXNG too. Like I said degoogle.
Get a PGP encrypted e-mail. Check Protonmail out.
There's also Tutamail that doesn't cover PGP, but uses hybrid encryption that avoids some of the cons of PGP.
Skiff mail is also a decent option.
Use an e-mail aliasing service such as SimpleLogin or AnonAddy.
Check OpenPGP out. Claws Mail is a good e-mail client for Windows and Linux, Thunderbird for Mac OS.
Gpg4win is free and easy to use for anyone that wants to encrypt/decrypt e-mails.
Instead of Whatsapp, Facebook messenger, Telegram etc. use Signal for your encrypted insant messaging, voice and video calls.
Get a metadata cleaner.
Get a firewall like Opensnitch, Portmaster or Netguard which can block Internet for trackers.
Alternatively, go with a private DNS that blocks these trackers. NextDNS is a good paid service. Rethink a good free option.
Replace as many of your applications as you can with FOSS (free and open source) ones. Alternativeto can help you.
Always have automatic updates on. They are annoying af, I know, but they are necessary.
Keep your distance from outdated software.
Always have two-factor authentication (2FA) enabled.
Do not use your administrator account for casual stuff. If you're on Linux, you probably know you can be sudo, but not root.
On Linux distributions use AppArmor, but stay away from random antivirus scanners. Other distributions default to SELinux, which is less suited to a beginner.
Never repeat your passwords. If you can't remember them all, use a password manager like KeePass.
Encrypt your drive.
Honestly, VPNs have their uses and ProtonVPN, Mullvad and Windscribe are decent, but eh. If you don't trust your ISP, why would you trust the VPN provider that claims they don't log you when you can't verify such a thing?

There was this post I saw a while ago about people who say "if it's physical media you'll always have it unlike digital media". I find this most irritating when it's said about PC games.
First of all, you know you gotta make backups, right? I do, and I'm still to lazy to back up most of my games as isos. (I have ripped all my music CDs though!)
Then of course, you start to run into copy protection and DRM! The most basic kind is that some discs just come with intentionally-bad sectors to make disk copying software balk. That's not that bad because there are programs that you can just tell to keep going after read errors. But it only gets more complex from there.
Often, the game files are encrypted, and are read using special drivers, which Windows dropped support for because of security issues. So you have to find (and back up) a crack for your game. Or you put Windows into test mode so that it lets you run some rancid old drivers. I'd trust the cracks more.
Of course, compatibility problems are always a thing that can happen, but it feels extra galling if it's only because of DRM.
And some later DRM got really draconian. Like, you have to connect to a server to activate your game (is it still running?) and you have a limited number of computers you can ever activate it on (which hardware upgrades constitute a "new computer"?), and after that maybe they have a hotline you can call to get more activations.
Then there's patches that you may have to find, after the official website of the game is gone. Even if you have some later gold edition version or whatever. I've got a Baldur's Gate 1+2 collection that randomly lacked the very last patch for BG1. There's a game-breaking bug that can trigger on a completionist playthrough with the expansion. Luckily, I still found the patch and could continue.
What I'm saying is, if you have a game on Steam and it doesn't depend on any non-Steam servers to run, there's a good chance that it's more future proof than a disc on your shelf.
Even better of course is a DRM free copy (on disc, from GOG or the high seas) with a backup.

Physical media discourse on here feels... weird (this is a long post)
I agree on a fundamental level that the move towards drm-based streaming licenses is bad, and that the perpetual-personal-content license (read: the license most DVDs are under) is a thing we should maintain, at least as a stopgap until the vanguard of communism empowers us to rewrite IP law.
That said, the language positioning Physical vs Digital, the insistence that anything other than physical media is bad, and the upholding of DVDs as a gold standard, all read to me as kinda tech-iliterate, and thus ignorant of the real issue at hand.
The primary issue with streaming, which folks on Tumblr *have* correctly identified, is to do with Access control.
The primary issue with streaming is that it requires a regular subscription payment, to exclusively view content under a license that can be revoked at any time for any reason.
This is the mechanism by which Netflix can kick you off your friend's account, this is also the mechanism by HBO can scrub Infinity Train from existence as a tax write-off.
This system is unequivocally bad, and the reason it's bad is because of DRM and Access Control. This may seem pedantic, but is an important distinction.
Let's take a look at DVDs now. Most DVDs are distributed under a license that grants you perpetual access to view in a private setting, but not to redistribute the content.
This is what that FBI warning that plays at the top of every DVD is trying to tell you, and is why ripping a DVD, while simple, is technically illegal.
Because the video file is hard-encoded into the DVD, and its proliferation largely predates the IOT zeitgeist, *most* DVDs don't contain any access control measures beyond that legal text, but this is not universal.
youtube
This is a great video outlining FlexPlay, an ill-faded technology that used a disk with light-sensitive material, that over the course of about a week or two, blacked out the disk rendering its contents un-viewable.
I bring this up because it highlights two issues.
One, DVDs aren't a physically resilient technology.
Disks are fragile, and even moderate scratches or damage can render a disk unreadable. This is a point of contention retro gamers have had for years, because while their NES cartridges still work, their PS1 disks don't.
This is not even to mention how the plastic of every broken disk still exists somewhere in the world, and will for centuries.
Two, it shows that IP conglomerates, have been at this for years, and won't be stopped in putting Access control into DVDs.
This means that buying DVDs of new shows forever is not an end-game solution. Unless you are content to stop consuming new media, eventually you're going to encounter a DRM protected disk.
To use another more recent example, remember when the Xbox One came out? They had this giant controversy over how playing a game locally on the disk still required online access to Microsoft's servers.
Your physical media could be locked right up for any reason by the platform itself. How can we trust that if DVDs or Blu Ray made a comeback that they would not suffer the same fate?
So where do we go from here, if physical media isn't safe?
Let's consider what digital video *is*. It's a file, same as any other. .mp4 .mov
Some, like .mp4 support DRM-encryption (although don't always contain any). Others, like .ogv exist free from DRM, thanks open source software developers.
Likewise, with a DRM encrypted digital file, because all of the data is hosted locally, just encrypted, there are ways to remove or bypass that encryption, because the VAST majority of cyber-security depends on a lack of knowledge.
This website has a number of very good resources both on drm-free digital storage mediums, and the process of removing certain types of DRM from digital files, (and was my primary resource for this paragraph)
https://www.defectivebydesign.org/so_youve_got_some_questions_do_you#:~:text=To%20avoid%20DRM%20and%20other,webm)%2C%20or%20Daala.
Storing your media as unlocked files presents the best of both worlds.
You have full control over access to your media, you own those files just as much as you own the hard drive you store them on.
You can buy media online, so long as the distributor gives you a media file instead of a streaming portal. You can also choose to obtain media files through other means, that's none of my business.
And you can do some really cool stuff like setting up a self-hosted media server, allowing you streaming-like remote access to all of your media, without ceding any ownership over that media. (Jellyfin is the most popular open-source solution but there are others) https://jellyfin.org/
And absolutely none of this is to mention the ways in which you can SUPPORT YOUR LOCAL LIBRARY, WHO MOST LIKELY HAS STREAMING OPTIONS.
In the US most public libraries maintain Kanopy and hoopla memberships, allowing you to access streamed content from your local library.
This has the added benefit of keeping the library's usage statistics up, which often helps them with securing more funding.
While you don't own the media, you also don't have to pay for it, and you crucially don't have to give your money to streaming services and IP hoarders.
It requires 0 technical background, and presents a more sustainable and equitable view of what streaming can look like.
So in conclusion:
Make sure you own the content you're paying for, and accept nothing less.
Don't be convinced that your DVDs are immune.
Learn some basics about networking, filetypes, cyber security and self-hosting if you really care about this stuff.
Support Open Source Software
Support Your Local Library

ACCESSING ARCHIVED DATA…
Character Archive I : TREV (part 1) User: Data under non-disclosure - Property of ENCOM 1984 Developed in 1982 OPEN FILE? (Y/N)?
Program Function: Originally designed to be a language translator program, the User of Trev realized during development that his program’s analysis function was surprisingly better than functional, and would actually be far better suited for a Program Maintenance Software. Within the system this User was designing programs, Trev had come to know the Open Server as an equally dangerous yet diverse culture to grow in. During his youth, Trev had gotten to know many of the programs that came and went, from those simply passing through the system, to patients that were sent from long distances to be under his care.
With the Open Server, Trev spent his free time ice skating in the icy flatlands of his server, or doing research on User Biology. He was captivated by their methods of in using physical means to treat patients, whereas the standard was to access the program’s data. In Trev’s server, that data was accessed not through Identity Disks like on The Grid, but rather a slot that could be accessed on the back of their neck. Since the means of treatment already had a somewhat physical element, Trev believed that a marriage in User and Program techniques could create medical breakthroughs for Programs, and potentially help overcome their fragility/prone to derezzing entirely from a single major injury.
After Kevin Flynn learned of Trev during a business meeting, he had tracked down Trev’s User and spoke with him. Flynn was very impressed with his skills, and offered a position at ENCOM, but for unknown reasons, he had refused. Rumors surfaced about the possibility of the User being on the run from Russian Officials, but nothing was ever confirmed, as the User had vanished not long after Flynn had met him. Whether he was caught or had went into hiding is unknown, and Kevin Flynn himself was adamant about not disclosing the User’s identity, in case the latter belief was true, and had officially wiped all records of the User, or had identifying code lines deeply encrypted, leaving only the designed Programs and Flynn himself to truly know said identity. Before the User had vanished, Flynn paid an unknown sum to select five programs from the User’s roster so he could integrate them into his own developing system. Within the Server, many programs had heard rumors of The Grid, but only whispers of energy and data going to a property that was marked as belonging to Kevin Flynn, but would quickly disappear into encrypted territory that nobody could pass through or even take a peek at. So when the famed User presented himself via text commands, explaining his plans to give five chosen Programs the option to leave their server and join The Grid, the reaction was very mixed. Trev was one of the chosen programs, and after seven Cycles of deliberating (24 Hours in the User World), he made his decision to leave his home and accept the offer. By this time, Trev had been Two User Years old (1Deca4Xila Cycles to be precise) and had seen a great deal—much of it, to his dismay, in the confinements of Civil War. To him, despite leaving home and all his beloved friends, those who he would call family, it was the new start he had been yearning for for nearly a DecaCycle.
On the trip back, he had learned something in those 5.5 Cycles (19 Hours in the User World). Kevin Flynn was one of the most Exhausting Users Trev had ever encountered.
He had talked nearly the entire time. It didn’t occur to Kevin Flynn as he was transfixed with the dialogue commands he had been exchanging with Trev, that while it had only been hours for him, for Trev, entire Cycles were going by. Cycles are a Program’s standard day. And each unit of User Time was 7x longer for a program (i.e. 1 second = 7 Nanos 1 minute = 7 Micros, etc.); to conclude: Trev did not get much rest during the trip. (Each Program got to travel in their own personal flash drive) In fairness, Trev supposed a User would find a Program being fascinated with physical anatomy to be a little strange. It seemed curiosity was a plague he and Flynn had in common—even if he was a little insufferable.
Upon arrival to The Grid, Trev could not deny the beauty in it. The architecture, the size of it—it truly was a vision. The newly integrated Programs were all given suits, as well as Identity Disks.
Trev found them to be far too slimming and uncomfortable—why was everyone walking around with lightlines bared like a newborn with suits that hugged the body so tight you could see every curve on the body? He didn’t care if the overall climate was warmer, he would have liked to have pants, at least. Furthermore, when Trev was invited to The Grid, he was under the impression that this very large system was going to be a professional environment. So, it was safe to say, when he was told after settling in to his new apartment that there was a welcome party in the best nightclub in town…
…this was not the environment he expected.
Parties were not Trev’s scene.
But the mood shift did catch his attention, particularly when a group of programs began to walk in. He had heard whispers of a famous Security Program, “Tron” was his name.
Most Programs tended to stare at Tron, who wouldn’t stare at a legendary program, but someone else had actually caught Trev’s eye, that late Cycle. He was never one to believe in falling in love, or Programs being made while having a specific Counterpart out there to be their other half…
But something made everything slow down, in that moment…
…and he was awestricken.

Idk how to explain this without being long-winded, but it’s my blog so whatever.
Basically, I have a 2011 MacBook Pro 15”. I’ve replaced the battery and upgraded the RAM and replaced the 500GB HDD with a 500GB SSD. It’s great! The machine is truly the fastest mobile computer I have.
The 2011 MBP was let go from software updates a while ago, meaning, natively, macOS High Sierra is as high as I can get the thing.
Luckily, this computer is from an era when Apple actually made computers and not eWaste, so I just erased macOS off of it and flashed Zorin OS (an Ubuntu-based Linux distro) onto it. The computer is now even better! It’s my primary productivity machine. The display, speakers, battery life, and thermals are all pretty bad, but it’s just so snappy and problem free I can’t help it.
Now, when I set up Zorin OS I used LVM Encryption to encrypt the entire disk. Basically, upon booting, before anything happens, I’m prompted with a password box. Once I put in the encryption key, the computer would continue booting and bring me to my usual login screen. Great! Easy peasy, extra secur-sy. Well. That was the case.
Somehow, in my efforts to find a way to stop Linux from using my MBP’s Discrete GPU in favor of its Integrated (more efficient, less power hungry) one, I broke something in the EFI or SMC idk. Reinstalling didn’t help. MacOS Recovery mode didn’t help. The only way I fixed it was by wiping the device, running the installer USB, downloading the script I used to fuck it up, and then running it to undo what I previous had it do. This worked. Luckily, I was keeping the machine backed up with Timeshift. So, I wiped the computer again and installed Zorin OS, fresh, reinstalled Timeshift, and restored from backup. The only problem?
When I reinstalled Zorin, I didn’t use LVM Encryption because I was tired of having to manually type in that 25 randomized character password I chose. As a result, now every time I boot the computer, I’m prompted with a “Waiting for encrypted device, (name).” That prevents the machine from booting for about 5 minutes until it just randomly decides “ope, never mind” and finally takes me to my login screen. It does nothing in prohibiting me from using the computer expect prolong it. It’s just annoying and weird as hell, and I have no idea how to get rid of it.
Clearly, the way Timeshift resorted the device has it thinking it’s still an encrypted volume, and I have no idea how to tell it that it is not.
But anyway, it just aggravates me, and I needed to ramble and vent about it. Carry on.

Building a Resilient SAN Storage Architecture: Strategies, Best Practices, and Future Insights
Designing a Storage Area Network (SAN) that's robust, secure, and highly available is a crucial mandate for any IT infrastructure leader. Resilient SAN storage architecture forms the critical foundation for enterprise applications, minimizing downtime and safeguarding data integrity, even under adverse conditions. Whether you manage a global data center or architect solutions for mission-critical workloads, understanding and implementing resilience in SAN design ensures business continuity, empowers rapid recovery, and protects valuable assets.
This guide provides an in-depth look at building a resilient SAN storage architecture. We’ll break down core considerations—including redundancy, failover mechanisms, data protection strategies, and performance optimization. You’ll also learn best practices for implementation, explore real-world examples, and get a glimpse of the evolving trends shaping the future of SAN storage technology.
Core Considerations for a Resilient SAN Architecture
A resilient SAN does more than store and shuttle data; it assures continuous, reliable access regardless of IT failures or disruptions. Let's explore the essential pillars:
Redundancy and Failover Mechanisms
At the heart of SAN resilience is redundancy. Eliminating single points of failure requires careful attention to:
1. Multipath Connectivity
Deploy redundant host bus adapters (HBAs), switches, and storage controllers. Multipath I/O (MPIO) software facilitates multiple routes for data traffic. If one path fails, traffic seamlessly shifts to another. Leading enterprise SAN setups utilize dual fabrics to segregate traffic and provide additional protection.
2. Dual-Controller Storage Arrays
Choose arrays with dual-active controllers that support automatic failover. If a controller or module fails, its counterpart takes over operations instantly, preventing application downtime.
3. Power and Environmental Redundancy
Implement uninterruptible power supplies (UPS), generator backup, redundant cooling systems, and protected cabling paths. Data centers should leverage multiple electrical circuits and separate cooling zones to prevent environmental threats from causing cascading failures.
Data Protection Strategies
Protecting critical data against corruption, loss, or cyberthreats is non-negotiable.
1. Snapshot and Replication
Schedule regular snapshots to capture point-in-time data states. Leverage synchronous and asynchronous replication to offsite data centers, ensuring copies of your data are always available even during local failures or disasters.
2. RAID and Erasure Coding
Implement RAID levels (typically RAID 6 or 10 for write-heavy environments) to protect against disk failures. For scalable, distributed SANs, erasure coding provides high availability and fault tolerance with reduced storage overhead.
3. Encryption and Access Control
Use data-at-rest and data-in-motion encryption (such as AES-256 and encrypted Fibre Channel) to guard against interception and unauthorized access. Couple this with multi-layer authentication, role-based access, and rigorous audit logging.
Performance Optimization
A resilient SAN must also support consistently high performance—for applications, slow storage is as problematic as outages.
1. Storage Tiering
Divide workloads across SSD, NVMe, and HDD tiers based on IOPS requirements and latency sensitivity. Automated tiering ensures hot data resides on the fastest media.
2. Caching and QoS Policies
Leverage controller caching for rapid reads/writes and implement Quality of Service (QoS) to prioritize bandwidth for the most critical workloads, minimizing the risk of resource contention.
3. Network Considerations
Deploy high-speed, redundant networking (16/32/64 Gbps Fibre Channel or 25/40/100GbE iSCSI) and manage zoning to reduce traffic bottlenecks and limit fault domains.
Best Practices for Implementing a Resilient SAN
Translating architectural principles into action requires meticulous planning, rigorous testing, and adherence to leading industry standards.
1. Assess and Document Requirements
Whether supporting SAP HANA, SQL Server clusters, or VMware virtualization, start by thoroughly documenting application SLAs, growth projections, and recovery objectives (RPO/RTO).
2. Follow a Modular, Scalable Design
Design modular SAN blocks that can be expanded non-disruptively. This avoids forklift upgrades and future-proofs the infrastructure as storage needs grow.
3. Implement Comprehensive Monitoring
Deploy advanced monitoring and analytics tools capable of proactive alerting for hardware failures, latency spikes, and security anomalies. Use real-time dashboards to visualize health across fabrics, switches, and storage arrays.
4. Validate Disaster Recovery Plans
Test disaster recovery (DR) scenarios regularly, including complete failovers, partial outages, and cyberattack simulations. Document lessons learned and refine processes for faster, more reliable recovery.
5. Maintain Regular Firmware and Security Updates
Patch vulnerabilities promptly and keep software up to date on SAN controllers, firmware, and management appliances. Automate compliance reporting where possible.
6. Train Staff and Enforce Change Management
Ensure administrators are certified and up to date on SAN protocols, multipathing, and data protection. Implement strict change control processes to minimize misconfigurations and accidental downtime.
Real-World Examples and Case Studies
Examining successful SAN implementations sheds light on practical strategies for resilience:
Financial Services Firm Enables Zero Downtime
A major bank re-architected its SAN using dual-fabric topology, controller-based redundancy, and automated failover. Continuous replication between primary and secondary data centers enabled seamless disaster recovery. After a localized power failure, the institution experienced zero downtime, preserving customer trust and regulatory compliance.
Healthcare Organization Protects Patient Data
A hospital deployed a tiered SAN with encrypted fibre connections and real-time snapshots. During a ransomware attack, IT restored clean data within minutes from immutable backup snapshots, avoiding operational disruption and regulatory penalties.
E-Commerce Enterprise Scales on Demand
A global retailer leveraged a modular SAN design, expanding storage in response to seasonal spikes without service interruption. Automated tiering ensured critical web transactions always ran on low-latency NVMe storage, improving customer experience during peak sales periods.
Future Trends in SAN Technology
Staying resilient means staying ahead. Here are the key trends shaping next-generation SAN architectures:
NVMe over Fabrics (NVMe-oF)
NVMe-oF enables ultra-fast, low-latency connections between hosts and storage, eclipsing legacy protocols. Early adopters have reported substantial improvements in transactional database, VDI, and AI/ML workloads.
Software-Defined Storage (SDS)
SDS decouples storage services from hardware, enabling greater agility, simplified management, and easier scaling. Many SAN vendors are integrating SDS into their platforms, blending traditional arrays with cloud-like flexibility.
Autonomous Operations and AI-Driven Analytics
AI-powered analytics now predict failures and optimize placement dynamically based on workload analysis. Some platforms even automate healing of degraded resources and proactively rebalance traffic.
Greater Integration with Hybrid and Multi-Cloud Environments
SANs are increasingly designed to connect with cloud object storage or DRaaS platforms. Transparent data movement between on-prem and cloud locations supports advanced backup, disaster recovery, and compliance needs.
Enhanced Cyber-Resilience
Immutable storage snapshots, micro-segmentation, and end-to-end encryption are becoming required capabilities as cyber threats evolve. Future-proof SANs are those that can isolate, recover, and protect against sophisticated attacks.
Maximizing Uptime with Resilient SAN Storage Design
The drive for digital transformation has made designing for resilience in SAN architecture not just a recommendation, but a business imperative. Robust redundancy, rigorous data protection, efficient performance optimization, and diligent implementation all play crucial roles in achieving non-stop IT operations. Real-world success stories and emerging innovations illustrate how forward-thinking organizations keep their data accessible, workloads performant, and downtime to a minimum.
To remain competitive, IT leaders must continually assess, adapt, and iterate their storage architecture strategies. Investing in resilient SAN solutions today is essential to safeguarding tomorrow’s opportunities and business continuity.

Great question — and let me tell you, the truth is way more interesting (and a bit scarier) than most people think. Just because you delete something doesn’t mean it’s gone. Let’s break it down:
⸻
What REALLY Happens When You Delete Data
1. File Deletion Isn’t True Destruction
When you hit delete, your device:
• Removes the reference to the file in the file system index (kind of like tearing out a page in the table of contents)
• BUT the actual file still exists on the disk/SSD until it’s overwritten by new data
This is like taking your name off a mailbox but leaving the mail inside. Anyone who knows how to check the box can still read it.
⸻
2. What About the Trash/Recycle Bin?
• On most systems, deleted files go to a temporary folder (Trash or Recycle Bin)
• Not actually deleted until you empty the bin
Still recoverable at this point with basic tools.
⸻
3. Even After Emptying the Trash…
• On traditional HDDs (spinning hard drives), data can often be recovered using forensic tools unless it’s been securely overwritten.
• On SSDs, things get weirder due to a process called TRIM, which helps with wear-leveling and may mark the data for deletion more efficiently — but even then, recovery might still be possible in some cases.
⸻
4. Who Can Still See Your Deleted Data?
• Hackers using data recovery software
• Forensic analysts during investigations
• Even some apps or system services might still store metadata, previews, or cache versions elsewhere
⸻
5. Want It REALLY Gone? Here’s How:
a. Overwrite It
Use tools like:
• CCleaner (with secure erase)
• BleachBit
• Mac’s Disk Utility (secure erase options for drives)
b. Encrypt First, Then Delete
If data was encrypted, deletion is more final because the key deletion = permanent loss.
c. Use “Secure Delete” Tools
Programs like:
• sdelete (Windows)
• shred or wipe (Linux)
• FileVault (macOS encryption)
d. Physically Destroy the Drive
If you’re going full CIA/NSA mode — smash, drill, or melt that sucker.
⸻
TL;DR:
“Delete” doesn’t mean “destroy.”
The data lives on — in limbo — until it’s overwritten or securely wiped.
⸻
Want me to show you how to securely wipe files from your Mac or external drive? Or how hackers can recover deleted files in forensics? Let’s go deeper if you want!

Back end Web Development: 5 Best Measures for a Secure Website
No matter how advanced features you use in back end web development, there are high chances that your website can be attacked by malware, hackers, or users. Such attacks enable fraudulent people to gain access to confidential data, like bank details and health-related information. Cyberattacks not only harm users, but they also spoil the reputation of developers.
So, if you are a developer, you must know reliable ways to strengthen your back end security.
Having taken this fact into account, we have written this blog to familiarize you with the 5 best ways to make your back end strong enough to keep cyberattacks at bay.
Top 5 Methods for Secure Back end Development:
As a developer, if you adopt the following practices in back end web development, you will considerably reduce the chances of unauthorized access to your website:
Multi-Factor Authentication:
Multi-factor authentication (MFA) means adding extra steps for the authentication of a user during login. Let’s get a clear idea of MFA with the example provided below:
Google or Facebook may send a code to the user’s phone number when they sign in with their email, or they may need a biometric scan.
Thus, an additional layer of protection is added, which is better than the usual password and email methods.
Data Encryption:
Personal data, credit card details, and passwords must be kept confidential, as they are sensitive information. In fact, such details must not be stored in the database in their plaintext format. Doing so is as foolish as leaving your door open with the line, ‘come in and steal whatever you want.’
Keep in mind that if data is hacked, all sensitive data will be leaked. To cope with this issue, rely on encryption.
Encryption is like keeping your door locked with a strong key. It scrambles the data so well that it becomes beyond understanding. Even if somebody breaks in, they will not be able to understand what it says. Thus, you can keep your sensitive information safe.
The following are some encryption methods used in back end web development for indubitable security:
Hashing: It converts data into a fixed-length string.
Asymmetrical encryption: With a pair of keys (private and public), asymmetric encryption enables encryption and decryption.
Symmetrical encryption: It utilizes a single key for encryption as well as decryption.
These encryption techniques can allow you to miraculously improve the security of your back end web applications and protect confidential data from fraudulent access and leaking.
Disaster Recovery and Data Backup:
A wise back end development strategy is incomplete without regular data backup and disaster recovery. If a physical loss of data happens, for example, a hard disk failure, or software data loss, like a storage error or damage because of malware, data recovery is possible with backup.
Ensure that you choose backup software and fix a backup schedule, like daily, weekly, or monthly. Your backup methods must have full backups, incremental backups, and differential backups.
Proper Validation and Sanitization:
It’s foolish to trust the input provided by the user. In other words, you’d better assume that any data given by users may be malicious without proper validation and sanitization.
Validation means checking whether the input provided by the user harmonizes with the expected format, type, and constraints.
If there is a form field for an email address, validation will ensure that the input sticks to the correct email format, and it’s not just normal text.
Sanitization means the removal and modification of harmful elements or characters from the user input for the prevention of security vulnerabilities. For instance, if you eliminate HTML tags from user-generated input, it can stop cross-site scripting attacks.
That’s why validation and sanitization are a must-have in back end web development.
Authorization and RBAC:
Authorization means determining whether a user is permitted to do a particular thing on a specific resource. However, it’s wise not to allow some users to get some permissions. It’s because limiting permissions leads to reduced risk. The fewer the permissions are, the smaller the attack surface is. Thus, the fraudulent people can’t take advantage of vulnerabilities. That is where Role-Based Access Control (RBAC) is required. RBAC is a mechanism to control and manage access to resources according to the user’s role in organizations. That’s why businesses look for it when they hire Angular development services.
In a usual website, there is an administrator with full access to all resources, and a user who can view their own data.
RBAC makes sure that each user can only do those things that are allowed to them according to their given role. Let’s get it clear with an example below:
A user is not allowed to modify the data of another user or have access to administration functions. When such permissions are limited according to the requirements, the risks of data breaches and unauthorized access are reduced to a large extent.
Conclusion
The 5 best ways for safe back end web development are multi-factor authentication, data encryption, disaster recovery and data backup, validation and sanitization, and authorization and RBAC.
By using these measures, you can reduce the chances of a cyberattack on your website.
