With Citrix's change to their pricing structure, alternative remote access solutions are important: but security is always #1. Security breaches can lead to significant financial losses and damage to your reputation. Here are five best practices to ensure your software delivery remains secure as we move into the end of 2024. 1. Implement Multi-Factor Authentication (MFA) Passwords alone are no longer enough to protect against unauthorized access. MFA adds an extra layer of security by requiring users to provide two or more verification factors. 2. Employ End-to-End Encryption Ensure that data transmitted between your servers and clients is encrypted to prevent interception and tampering. Use encryption protocols like TLS and keep your cryptographic keys secure. 3. Regular Security Audits and Penetration Testing Regularly assess your systems for vulnerabilities through security audits and simulated cyber-attacks. Schedule quarterly audits and consider third-party assessments for unbiased evaluations. 4. Keep Software Updated Outdated software can have unpatched vulnerabilities that are easy targets for hackers. Implement automated update systems to ensure all software components are up-to-date. 5. Educate Your Team Human error is often the weakest link in security. Regular training ensures that your team is aware of the latest threats and how to avoid them. Conduct monthly security briefings and provide resources for continuous learning. For help contact us: https://lnkd.in/eA7BSQYE

"IBM i/AIX/IBM Power Virtual Server during Holy Week: Recommendations Dear colleagues, I remind you that during these 2 weeks, many hacking, phishing, and ransomware attacks tend to occur. Please take your precautions: * Make full backups whenever possible. * If you can take snapshots and exports, it wouldn't hurt. * Verify that your backups can be restored. * Check for the latest security patches. * Monitor access logs. For those using VTL (Virtual Tape Libraries), IBM Spectrum Protect, or any backup software: * Having a second backup mechanism or creating an export can save us from unpleasant surprises. * If feasible, save data to disk and then to a cloud bucket. * VTLs allow tape-out to physical cartridges (requires an on-premise VTL): It's not a bad idea to store critical data in another type of medium. * ICC (Save to disk and then to the cloud) is not my favorite, but along with BRMS, it can be an alternative to VTL. * Remember that VTLs are software-based solutions: Don't forget to install the latest patches and review security. For those with IBM Power workloads in the cloud: It's not a cheap web-hosting; you won't find N snapshots to revert to a point in time on any day of the last week. It's the users' responsibility to back up and keep the workloads available. If you use software/hardware replication, test that they don't have delays. Some products like Mimix allow rollback to a certain point in time in case of contingencies (or attacks). TURN OFF TEAMVIEWER, ANYDESK, CHROME REMOTE DESKTOP, or any other CLOUD-BASED remote control mechanism for which you are not responsible for security. A well-configured VPN or SSH access can be more secure. If you need assistance, don't hesitate to ask for help."

𝗛𝗼𝘄 𝗦𝗦𝗛 𝗪𝗼𝗿𝗸𝘀? SSH, or Secure Shell, is the go-to protocol for establishing a safe connection to remote machines, even over networks you might not entirely trust. It achieves this by encrypting all communication and offering several methods to verify who's connecting and how data is exchanged. While there have been two versions (SSH-1 and SSH-2), it's the latter, standardized by the IETF, that's widely used today. SSH-2 operates across three core layers, each with a distinct role in ensuring a secure connection: 𝗧𝗿𝗮𝗻𝘀𝗽𝗼𝗿𝘁 𝗟𝗮𝘆𝗲𝗿: This is the foundation, providing encryption, integrity checks, and data protection. Think of it as the secure tunnel through which everything else travels. 𝗔𝘂𝘁𝗵𝗲𝗻𝘁𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝗟𝗮𝘆𝗲𝗿: Here, the client's identity is confirmed. Only those with the right credentials gain access, keeping unauthorized users out. 𝗖𝗼𝗻𝗻𝗲𝗰𝘁𝗶𝗼𝗻 𝗟𝗮𝘆𝗲𝗿: Once the connection is secure and authenticated, this layer takes over, efficiently managing multiple communication channels within that single encrypted connection. In essence, SSH is the secure gateway that enables system administrators, developers, and others to manage and interact with remote systems with confidence, knowing their data and commands are protected. #SSH #cybersecurity #networking #IT #Linux #sysadmin #linuxcommands #linuxfoundation #linuxadmin #linuxkernel #linuxtips #linuxadministrator #linuxsecurity #linuxengineer #kali #kalilinux #infosec #cybersecurity #cybersecuritytips #pentesting #redteam #informationsecurity #CyberSec #networking #networksecurity #infosecurity #cyberattacks #security #linux #cybersecurityawareness #bugbounty Image Reference - ByteByteGo
