Most SSH hardening advice ends at the same recommendation: Disable password authentication and use SSH keys. . That's good advice. It removes entire classes of attacks, including password spraying, credential stuffing, and brute-force attempts against exposed servers. The problem is what happens next. Many administrators treat SSH keys as the finish line when they are really the beginning of the hardening process. Attackers rarely care whether they obtained access with a password or a private...

How to Secure My NetworkPrice Tag 1security advisory remote access

Most of the time, nobody notices. SSH authentication succeeds, no alerts are generated, and the connection looks exactly the way it did the day the key was installed. That's part of the problem. . When security teams investigate unauthorized access on Linux systems, they often focus on passwords, exposed services, or vulnerable software. Trusted access receives less attention. Yet a single forgotten or unauthorized SSH key can provide the same access as a legitimate user while attracting very...

IDS VS IPS Esm H350
How to Secure My NetworkPrice Tag 1intrusion detection application security

The wrong IPS rule can look like a security fix right up until it becomes an outage. . On Linux systems, detection and prevention are often discussed together, but they do not carry the same operational risk. One tells admins that something suspicious happened. The other can decide whether traffic is allowed to continue. That is why IDS vs IPS is not just a definition to memorize. It is a deployment decision about where to monitor, where to block, and how much confidence a team needs before...

How to Secure My NetworkPrice Tag 1unauthorized access security techniques

Exposed SSH servers are continuously hammered by brute-force attacks, password spraying, credential stuffing, and recycled passwords from infostealer dumps. Attackers rotate usernames, test weak credentials, and probe for anything that gives them initial access. The logs usually look messy long before the compromise happens. . The difficult part is separating harmless failures from actual intrusion activity. One failed login from an internal workstation rarely matters. Repeated failures...

How to Secure My NetworkPrice Tag 1security advisory incident response

The first 30 minutes after discovering a compromised Linux server usually decide how much evidence remains available. One rushed reboot or cleanup attempt can wipe logs, terminate malicious processes, or remove network activity that investigators still need to review. Attackers also do not usually stay on one system for long once access is established. Early response is mostly about preserving visibility. Collect process information. Save network connections. Limit access carefully before...

Scraping Websites with Python and Selenium: Techniques and Tips

With advances in web development, web scraping has become more difficult than it used to be. Learn how to scrape data with Python and Selenium when emerging technology and other factors prevent standard scraping in this valuable tutorial. . Web scraping has been used to extract data from websites almost from the time the World Wide Web was born. In the early days, scraping was mainly done on static pages – those with known elements, tags, and data. More recently, however, advanced technologies in web development have made the task a bit more difficult. In this article, we’ll explore how we might go about scraping data in the case that new technology and other factors prevent standard scraping. The link for this article located at The Next Web is no longer available. . Discover the art of website data extraction with Python and Selenium in this comprehensive guide that delves into sophisticated techniques..
