Nearly every business today uses some Software-as-a-Service (SaaS) application. From streamlined productivity to team communication, web applications drive business revenue outcomes. Simultaneously, these applications expand your company’s attack surface since every connection creates new access points that threat actors can use to compromise systems and networks.

In the previous post, we’ve discussed how passive OS identification can be done based on different network protocols. We’ve also used the OSI model to categorize the different indicators and prioritize them based on reliability and granularity. In this post, we will focus on the network and transport layers and introduce a machine learning OS identification model based on TCP/IP header values.

Hybrid cloud security uses a combination of on-premises equipment, private cloud deployments, and public cloud platforms to secure an organization’s data, apps, and assets. It’s vital to the success of any organization that uses hybrid cloud network infrastructure. The key factors that make hybrid cloud security different from other types of security solutions are flexibility and agility.

The “fog of war” is a military term used to denote the uncertainty and confusion experienced on the battlefield. During periods of growing geopolitical conflict, it becomes increasingly hard to keep pace with new developments.

Properly configured firewalls are vital in any comprehensive cybersecurity strategy. However, even the most robust configurations can be vulnerable to exploitation by attackers. No single security measure can offer absolute protection against all cyber threats and data security risks. To mitigate these risks, it’s crucial to understand how cybercriminals exploit firewall vulnerabilities.

Optimally configuring “DisableIPSourceRouting” parameter enhances security by mitigating the risk of denial-of-service (DOS) attacks through packet spoofing. In such attacks, the goal is to inundate the target with high volumes of traffic, and using spoofed IP addresses makes it challenging to filter and identify the true source of the attack. Server hardening can be arduous. CSH by CalCom automates the process, learning your network to eliminate the need for testing.

The shifting sands of IT make the adage "you never know it all" ever more true as time goes by. I recall days when it felt like you could click through every major directory of Yahoo and know a little something about everything. I was a young man with a voracious reading appetite and an active imagination – both of which were thoroughly outpaced by the growth of the internet and my own developing maturity.

Cyber threats are getting smarter and are going after businesses of all kinds. Your first line of defense against these threats should be network firewall security, which protects your private data and systems. By filtering data based on set security rules, firewalls create a wall between trusted internal networks and untrusted external ones. A study from Cybersecurity Ventures says that by 2025, cybercrime will cost the world $10.5 trillion every year.
