Transport Layer Security is a security protocol used for facilitating seamless and safe communication between servers and web browsers. Put it his way, TLS encrypts data so that only the intended recipient and the sender can access it. Currently, TLS 1.2 and TLS 1.3 are the most commonly used TLS versions. After some major upgrades, TLS’s 1.3 version has emerged as one of the most extensively used and the safest security protocols for websites that need a high-end encryption service.

This policy specifies whether to prevent the redirection of data to client LPT ports during a Remote Desktop Services session. You can use this setting to prevent users from mapping local LPT ports and redirecting data from the remote computer to local LPT port peripherals. If a value is configured to Disabled or Not Configured, the attacker can leverage it to map the client’s LPT ports. In addition, he can use the port to redirect data from the Terminal Server to the local LTP ports.

NTLM is Microsoft’s old mythological authentication protocol. Although new and better authentication protocol has already been developed, NTLM is still very much in use. NTLM protocol has proven to have many flaws that result in potential vulnerabilities. One caution measure that can be taken is auditing and logging any NTLM traffic events.

CalCom Hardening Solution (CHS) is the ideal choice for IT Ops & CISOs looking to create a secured configured infrastructure.

CHS is a flexible hardening tool, with the unique ability to ‘learn’ where desired hardening changes will adversely impact production activity. CHS determines the impact of baseline changes before they implemented, producing visible conclusions for decision-makers. CHS eliminates time-consuming lab testing, reduces the cost and impact of hardening, and centering infrastructure control, thereby stopping security breaches and operational mistakes.

How Can CalCom Hardening Suite Make a Huge Difference In Server Hardening:

  • Cost effective server hardening process: Save time and resources required for testing security policies in lab environments.
  • Zero server outages: Ensure that production services are not harmed during server hardening.
  • Prevent & monitor unauthorized policy changes: Stop security breaches and operational mistakes before they happen.

Make Your Hardening Project Effortless.
