Cybersecurity: Building a Safer Digital Future

As digital technology becomes deeply integrated into everyday life, Cybersecurity has become an important part of protecting information, systems, networks, and connected devices. From personal accounts and online transactions to business operations and critical infrastructure, digital environments continuously handle large amounts of sensitive information. Maintaining their security requires awareness, appropriate controls, and continuous attention to emerging risks. Cybersecurity involves a broad range of practices designed to prevent unauthorized access, data loss, system disruption, and other forms of digital harm. Common approaches include strong authentication, access management, software updates, data encryption, network monitoring, and regular security assessments. These measures can reduce vulnerabilities and help organizations respond more effectively when security incidents occur. One of the major challenges in Cybersecurity is the changing nature of digital threats. Phishing attempts, malicious software, identity theft, ransomware, social engineering, and unauthorized access can affect individuals as well as organizations. As more devices become connected through cloud services, mobile platforms, Internet of Things technologies, and remote working environments, the potential points of exposure can also increase. Human behavior remains another important factor. Even advanced technical protections can be weakened by poor password practices, suspicious links, unauthorized software, or inadequate awareness. For this reason, cybersecurity education and responsible digital habits are increasingly relevant alongside technical safeguards. Looking ahead, Cybersecurity is expected to remain closely connected with developments in artificial intelligence, cloud computing, automation, and connected technologies. Organizations are likely to focus on identifying vulnerabilities earlier, improving incident response, and strengthening resilience across increasingly complex digital environments. Overall, Cybersecurity is not limited to a single technology or solution. It represents an ongoing approach to managing digital risks, protecting information, and maintaining trust as society becomes increasingly dependent on interconnected technologies. https://www.marketresearchfuture.com/reports/cyber-security-market-953

This job looks to still be archiving /var/lib/mailman instead of /var/lib/mailman3/ Not sure why it only started failing recently, or if its still needed after the mailman3 upgrade. ---------- Forwarded message ---------- From: "(Cron Daemon)" <mailman(a)lists.linuxfests.org> To: mailman(a)lists.linuxfests.org Cc: Bcc: Date: Mon, 16 Mar 2026 04:00:02 +0000 (UTC) Subject: Cron <mailman@scale-lists-centos9> /usr/local/bin/backup-mailman.sh Starting backup.... tar: /var/lib/mailman/: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: /var/lib/mailman/: Cannot open: No such file or directory tar: Error is not recoverable: exiting now Uploading backup.... /usr/local/bin/backup-mailman.sh: line 19: aws: command not found /usr/local/bin/backup-mailman.sh: line 19: aws: command not found rmdir: failed to remove '/tmp/tmp.mZNllZXzcU': Directory not empty

Details of changes

Just a record of changes for those of you who care about the infra: * Updated postfix on lists to strip DKIM/ARC headers for incoming messages. These get re-signed on the way out, and even when we have DKIM aligment to the new sig, some things don't like the old sig not verifying. * Updated mailman to always do DMARC From mitigation This will ensure we have DKIM alignment This also updated several lists that were doing Wrap based mitigation to do From mitigation * Updated SPF records To remove unneeded rackspace IPs * Updated our DMARC records Added some missing fields, removed rua/ruf addresses we don't need, added rua/ruf address for mailgun. * Updated DNS for lists.linuxfests.org Added an MX, rather than falling back to A record There's more to come, we need to move to enforcing our SPF/DKIM/DMARC policies, but I want to wait and make sure we're actually getting DMARC alignment first. -- Phil Dibowitz phil(a)ipom.com Open Source software and tech docs Insanity Palace of Metallica http://www.phildev.net/ http://www.ipom.com/ "Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Seuss
