    I'm a Penetration Tester and Cyber Security Specialist who is a professional in evaluating the security posture of Web-Applications (Websites) and ensuring the security of personal clients' online identities, accounts, devices, and networks, I've possessed my current knowledge through 3+ years of self-study and research plus 2+ years of work in the industry, protecting clients on a personal level and running vulnerability assessments against business websites, always leaving positive impression and impact, I hold a great record of being able to expertly provide the following services: - Perform comprehensive security checkups on Emails and Phone numbers and pinpoint security holes which often lead victims to be hacked with zero interaction nor awareness from them. - Assist in Account Recovery (Ex. Instagram, Facebook) - Educate thoroughly on the findings and remediations for a vulnerable target, equipping clients with enough information to trust themselves as they continue to utilize the technologies as normal with no fear of being targetted by hackers. - Investigate and educate on online frauds/scams, especially crypto ones, why and how they work, and how to distinguish between legit and not legit easily. - Clean up networks and devices from viruses/malware and ensure optimal patching for security. - Report fraud websites that impersonate legit businesses for a takedown. IMPORTANT: When it comes to cybersecurity-related services, there is a number of scammers not to be underestimated, whether within or outside of Upwork, therefore stay vigilant and keep in mind the following, 1. If you were scammed online via crypto, there's no one out there with the right to give a guarantee that they will be able to recover it for you despite how well furnished the so-called hacker's portfolio appears to be, the chance remains very slim and you should only pursue this kind of service for the sake of leaving no stone unturned knowing the high probability of failure, and you should only select a freelancer with a reputable profile and reviews to back up their activity because scammer accounts are usually fresh with no reviews and no verified ID, feel free to consult me to evaluate that. 2. Same applies to the request of hacking an account, there are complicated caveats that explain why it DOES NOT work the way you think it does but to keep it short, if you want someone's account hacked, aside from it being illegal and unethical and isn't the type of "service" I provide, the chance for it to work is about 1% to begin with, again, I'm available for consultation, account recovery is a different subject with a higher probability for success as long as it's your own account that was lost/hacked.

    For more than twenty years, I have been involved in the design, development, optimisation, maintenance, migration, and support of websites and servers. My expertise includes over eighteen years of specialisation in Joomla for both end-users and web design agencies. I have extensive experience working on numerous Joomla sites, including those with multiple languages. Throughout my career, I have successfully completed various Joomla-related projects. These include building new websites, ensuring responsiveness, creating AMP versions, migrating existing websites to Joomla, enhancing functionality, resolving security issues, installing SSL certificates, implementing HTTP security headers, managing user accounts and subscriptions, integrating payment gateways, removing malware, customising extensions and templates, developing custom extensions, optimising search engine performance, conducting search engine marketing, optimising content delivery, improving site speed, ensuring GDPR compliance, implementing various forms with anti-spam solutions, and utilising GeoIP services for auto field population. I also provide ongoing support, training, and any necessary measures to maintain the functionality, security, and stability of websites. Joomla Search Engine Optimisation services include producing search engine friendly URL's, meta descriptions and header tags combined with dynamic HTML and XML site maps, integrated with Google Search Console, Bing Webmaster tools, and Google Analytics as well as Privacy-respecting analytics such as Fathom and Matomo. I have a Matomo self hosted setup on my own server which clients use and find very useful as apart from not needing a degree in Google Analytics to understand it by default it tracks outgoing links from their sites. I possess extensive expertise in importing various types of website data into new and existing Joomla websites. This includes importing websites from HTML files, databases, and multiple Content Management Systems such as Drupal, Episerver, and WordPress. Additionally, I am well-versed in importing data from previous versions of Joomla websites. Since 2011, I've been utilising the Jreviews review and rating system to create custom themes and enhance functionality with features like advanced searches and notifications for updates in saved searches or user lists. I have extensive experience in customising the widely-used RSForm extension for numerous projects. This includes integrating forms with API's and external systems for various applications such as price comparison, quote creation, and e-commerce. I have also worked with multiple payment gateways in different currencies and utilised GeoIP services to automatically populate fields. I have extensively customised both the Eshop and Events Booking Joomdonation extensions within Joomla sites, working with online stores and event booking and ticketing for several years. My experience with both is vast. In addition to setting up, constructing, implementing, and overseeing Joomla-optimised cloud hosting and servers for multiple websites, I am proficient in managing various aspects such as firewall installation, virus and spam control, backups, migrations, and updates. I am well-versed in utilising Linux CLI, as well as working with Cpanel, Plesk, Hpanel and Spanel on a daily basis. Furthermore, I have experience with not only Apache and Nginx but also with LiteSpeed and OpenLiteSpeed Web Servers, particularly when speed is of utmost importance for a website. I possess servers and storage capabilities to duplicate a website onto a development environment. This allows for thorough analysis, debugging, updating, or development tasks to be carried out before transferring the changes back to the original source or a high-speed Joomla optimized hosting platform. I provide a Support Helpdesk Ticketing system with automated tasks in place, for example, client sites get monitored for availability. If a site is unavailable, a ticket gets created. Apart from documenting all work and changes, clients can report bugs, ask questions, and request additional features. I also work with clients using Project Management and Collaboration Tools such as Asana, Basecamp, Freedcamp and Teamwork. I can manage projects and teams or act as part of a team providing support both internally and externally on a clients behalf. I have excellent communication skills, my native language is English, and with an engineering background, I am extremely detail orientated. Security and confidentiality are paramount. I use secure email and chat environments with end-to-end encryption and use Bitwarden to share passwords with multiple users and organisations.

    With 14 years of industry experience, I began my career as a web developer, specializing in PHP with Joomla and later mastering WordPress, including WooCommerce. I have a deep understanding of database optimization to ensure peak performance. About eight years ago, I transitioned to Linux Server Administration, developing expertise in malware removal, including Blackhole exploits, Pharma hacks, redirection hacks, phishing hacks, and spoofing. I have successfully cleaned websites to secure Google approvals that clients were previously unable to obtain. This involved deep cleaning of codes and fixing issues that even top scanning tools did not detect. I started working with control panels like Plesk, WHM (CPanel), and VestaCP, before devising a fast and secure LEMP solution. This solution integrates advanced security measures, whether using CloudFlare or not, with tailored code snippets that enhance security and optimization, significantly improving site performance. I have extensive experience managing WordPress blogs and WooCommerce stores, providing comprehensive consultations from server selection to optimization, ensuring they can handle significant traffic loads, even during promotions, without encountering the white screen error in shopping carts. For Aapanel, I transformed it into a sophisticated product through meticulous configuration and research, tailoring it to meet user needs and ensuring responsive service. My skills also include performing security audits, conducting load stress tests, and monitoring and tracking server requests. I handle debugging, log management, and automate alerts. Additionally, I offer custom backup solutions for servers and websites, managing them across S3 buckets, Git repositories, Google Drive, or Dropbox, and I specialize in API integrations. I hold a diploma, a BTech, and an MBA in Information Technology, and have obtained numerous professional certifications from prestigious institutions including IBM, Cisco, Fortinet, Google, Oracle, Amazon, and I am also an Aviatrix certified ACE Engineer. My profile features an array of endorsements and testimonials from clients, all attesting to a 100% success rate in project delivery - feel free to review these testimonials to see what they have said. I am a member of respected associations such as NASSCOM, TiE, and CII, which keep me connected with industry trends and innovations. My role mandates a continuous pursuit of knowledge, ensuring that my clients' systems are always up to date and optimized. My problem-solving skills are frequently highlighted by clients, with one recent example where a client stated, "Before you, I conducted 10 interviews and none were able to grasp the issue, yet you not only understood it but also resolved it swiftly." My expertise has led clients to entrust me with managing their teams and servers, leading to enhanced team performance and product deliveries well ahead of deadlines. Working primarily in PHP/MySQL and the Laravel framework, I utilize tools such as VSCode, Git, NeoVim, and tmux. As a console enthusiast and productivity hacker, I focus on simplifying processes and extensively write automations to enhance efficiency. 🚀 Are you ready to take your project to the next level? Let’s collaborate and make it a reality! Over the years, I have developed a robust skill set across a diverse range of technologies and platforms. This includes expertise with various project management and collaboration tools such as Trello, Asana, Bitrix, and Basecamp; communication tools like Slack; and productivity suites like Google Apps and Zoho. Additionally, I'm skilled in email automation, Gsheets and setting up efficient workflows. My technical background also spans Platform.sh, Hugo, Netlify, Git for CI/CD, WP Engine, Vultr, Digital Ocean, Linode, AWS, GCP, Oracle, Godaddy, SiteGround, Bluehost, custom VPNs using OpenVPN, Lara Classified, and custom funnel systems in both Laravel and WordPress. More of other Keywords include DNS, DMARC, SPF, NS, Lightsail, EC2, Policies, GDPR, DB optimisation, Redis, MemCache, Fast-cgi, php-fpm, nginx, apache, page caching, load test, New Relic, Gridpane, Cloudways, tokens, composer, php-cli, wp-cli, Paypal, Stripe, GitHub, Bluesnap, ecommerce, healthcare, sales funnel, active campaign, telegram, whatsapp, blockchain, AI, crypto. 💼 While I am happy to work on an hourly basis initially to demonstrate my capabilities, I am particularly keen on establishing long-term relationships through monthly retainers, such as dedicating 10 hours a week to your project. Your success is my success, and I am eager to contribute to your journey towards achieving remarkable outcomes. ✉️ Message me today, and let’s kickstart our collaboration with your next project!

Encryption Basics: How It Works & Why You Need It

What is encryption and how does it work?

While IT security seeks to protect our physical assets—networked computers, databases, servers, etc.—encryption protects the data that lives on and between those assets. It’s one of the most powerful ways to keep your data safe, and while it isn’t impenetrable, it’s a major deterrent to hackers. Even if data does end up getting stolen, it will be unreadable and nearly useless if it’s encrypted.

How does it work? Encryption—based on the ancient art of cryptography—uses computers and algorithms to turn plain text into unreadable, jumbled code. To decrypt that ciphertext into plaintext, you need an encryption key, a series of bits that decode the text. The key is something only you or the intended recipient has in their possession. Computers are capable of breaking encrypted code by guessing an encryption key, but for very sophisticated algorithms like an elliptic curve algorithm, this could take a very, very long time.

Here’s a very simple example. Say you want to encrypt this sentence: “Protect your data with encryption.” If you use a 39-bit encryption key, the encrypted sentence would look like this:

“EnCt210a37f599cb5b5c0db6cd47a6da0dc9b728e2f8c10a37f599cb5b5c0db6cd47asQK8W/ikwIb97tVolfr9/Jbq5NU42GJGFEU/N5j9UEuWPCZUyVAsZQisvMxl9h9IwEmS.”

You can send that encrypted message to someone, separately share the key, then they’re able to decrypt it and read the original sentence.

If you send an encrypted email, only the person with the encryption key can read it. If you’re using an encrypted internet connection to shop online, your information and credit card number are hidden from unauthorized users, like hackers, illegal surveillance, or identity thieves. If you encrypt data before syncing it with the cloud, the cloud—or anyone breaking into it—can’t read that data. Even iPhones are encrypted to protect their data if they’re lost or stolen—something that has made headlines when organizations like the FBI or the NSA need access to them for investigations.

But encryption can be used for bad, too. Ransomware attacks are becoming more prevalent, also called denial of service (DOS) attacks that use encryption software to lock users out of their computers until they pay a fee.

Encrypting Data “In Transit” vs. Data “At Rest”

Basically, the data we encrypt is always either:

  • In transit, meaning it’s moving via email, in apps, or through browsers and other web connections
  • At rest, when data is stored in databases, the cloud, computer hard drives, or mobile devices

Encrypting this data is achieved mainly through:

  1. Full disk encryption (FDE): the primary way to protect computer hard drives and the at-rest data on them. Any files saved to the disk (or an external hard drive) are automatically encrypted. There are intermediate options for disk encryption, as well–folder encryption, volume encryption, etc.–that aren’t quite full-disk encryption, but in between.
  2. File encryption: a way to encrypt at-rest data on a file-by-file basis so it cannot be read if intercepted. This isn’t automatic, but it’s beneficial because that data will stay encrypted after it’s left its place of origin.
  3. End-to-end (E2E) encryption: obscures any content of messages so only senders and receivers can read it, like the early Pretty Good Privacy (PGP) email encryption software. The idea with E2E encryption is that it tackles all the vulnerabilities on the communication chain: the middle (intercepting a message during delivery), and both ends (sender and receiver). This is not just a niche offering anymore, either—platforms like Facebook Messenger and Apple’s iMessage have E2E encryption now, too.
  4. Encrypted web connections: via HTTPS, encrypted web connections use a Secure Sockets Layer (SSL) or transport layer security (TLS) protocols. With secure internet connections, we’re able to have better protected communications on the web. These aren’t impenetrable, but there’s less risk of exploitation. How it works: HTTPS uses SSL and TLS certificates when a browser and server communicate over the web. These are encryption keys, and when both browser and server have them, they’re authorized to access the encrypted data that’s passed between them. It’s a very basic, but very important, security measure when connecting to the web. If you’ve ever seen “https” instead of “http,” or noticed a lock in the URL bar of your browser, you’re accessing a secure site.
  5. Encrypted email servers: S/MIME (Secure/Multipurpose Internet Mail Extensions) public key encryption essentially gives SMTP (simple mail transfer protocol) email servers a leg up by allowing them to send and receive encrypted messages, not just simple text messages.
  6. Pre-encrypting data that’s synced with the cloud: there’s plenty of software available that can pre-encrypt data before it even gets to the cloud, making it unreadable by the cloud or anyone who hacks into it. Note that any files still stored on the local machine aren’t encrypted and are still vulnerable. This accounts only for files sent to the cloud encrypting tech.

Encryption can be simple, like secret-key, or incredibly complex, like the Advanced Encryption Standard (AES), depending on the algorithm and the length of the key. The longer the key, the more protection, but also the more processing power required to handle the encrypting and decrypting process.

A few types of encryption to know include:

  • Secret-key algorithms: Also known as symmetric algorithms, or private-key, this algorithm uses the same key for encryption and decryption. This is a touch more vulnerable because anyone who gets a hold of that one key can read anything you encrypt. Also, passing that secret key over internet or network connections makes it more vulnerable to theft.
  • Public-key algorithms: These are also known as asymmetric algorithms. With public-key encryption, there are two different, related encryption keys—one for encryption, and one for decryption. The public key is how the information is sent to you, and the private key decodes it (much like having a secure lock box on your front porch that a delivery person can put a package in, then only you can access that package with your private key). The benefit here is the key isn’t subject to being sent over insecure networks, but it does require more computer processing power so it’s a bit slower.
  • Block ciphers: Like the Triple Data Encryption Standard (DES), or 3DES, these encrypt data a block at a time. Triple DES uses three keys and is a pretty great encryption option for financial institutions that need to protect sensitive information.
  • Stream ciphers: A symmetric algorithm, it uses a keystream, a series of randomized numbers, to encrypt plaintext one character at a time. Rabbit, W7, and RC4 are popular stream ciphers.
  • Elliptic curve cryptography: A form of public-key encryption, it can be practically unbreakable for normal computers, or “hard.” This is security industry speak for technology that’s not completely unbreakable, but is generally accepted to be up to best standards.
  • Blockchain cryptography: Blockchain technology is essentially a type of distributed database, best known as the basis for Bitcoin, that uses cryptography to safely store data about financial transactions. Blockchain cryptography is a form of “cryptocurrency,” using public-key encryption, and it’s valuable in its ability to provide direct, trustworthy and fraud-proof transactions between users on a peer-to-peer network. Because blockchain databases are distributed, they’re more resilient in the face of a DOS attack, so more companies are exploring this.

A few popular algorithms include:

  • Advanced Encryption Standard (AES): A block cipher, this is pretty much the gold standard, per the U.S. Government. It offers 128-, 192-, and 256-bit encryption, the last two reserved for instances that require extra-strength protection.
  • RSA: This asymmetric algorithm uses paired keys and is pretty standard for encrypting information sent over the internet, although it’s been through some issues of getting broken, which have then been resolved.
  • IDEA (International Data Encryption Algorithm): This block cipher with a 128-bit key has a great track record for not being broken.
  • Signal Protocol: This open-source encryption protocol is used for asynchronous messaging, like email.
  • Blowfish and Twofish: Both of these block ciphers are free to use and popular among e-commerce platforms for protecting payment information. They were created by the same person and offer symmetric encryption with keys varying in bit length. Twofish is the successor and offers longer encryption keys.
  • Ring Learning With Errors or Ring-LWE: This protocol ramps up elliptic curves by adding in a new type of encryption that might be unbreakable by quantum computers.

What is key management and why is it important?

Key management is another important aspect of encryption. Keys are how all of that encrypted data becomes readable, so how you handle them is just as sensitive as the data itself.

Many businesses worry about this aspect of encryption—after all, if you lose an encryption key, you lose access to your data, too. That’s why key management dictates how keys are stored (and shared) so prying eyes can’t get a hold of them, making your entire encryption schema moot.

  • Diffie-Hellman key exchange: This secure way for people to create a key allows them to share secure information. This method is also touted as “perfect forward secrecy,” meaning that theoretically, at no point in the future can messages get encrypted with a Diffie-Hellman key be decrypted.
  • Double Ratchet algorithm: Based on the above, the Double Ratchet algorithm is a key management algorithm used in end-to-end encryption of instant messaging, like the Signal messaging app.

This article just scratches the surface of the art and science of encryption, but hopefully, it gives you enough basic understanding of this important security technology. If you’re considering enlisting the help of a data security expert, you’re in luck: there are plenty of IT services and IT security freelancers (as well as cyber security consultants) on Upwork with expertise in encryption who are able to consult with you on an encryption strategy that’s best for you and your data.
