Top Tips & Tricks
NNT is a proponent of ensuring that systems are fit for purpose, the art of configuring a system to be as secure as possible. In order to aid our customer’s in this endeavour, we utilize the research carried out by the Centre for Internet Security (CIS).
Those of you who use Change Tracker will know that Change Tracker Gen 7 provides the most accurate and effective solution to guarantee the integrity of your secure IT systems and reporting any changes as they occur.
The leaked NSA cyber weapon, EternalBlue, an exploit of Microsoft Windows that attacks SMB file-sharing services, was leaked by the Shadow Brokers hacker group last month and has since been used as part of the catastrophic WannaCry ransomware attack that started on May 12, 2017.
Understanding what the correct baseline configuration is for your IT system components is a keystone of security best practice. Compliance mandates, in particular, NERC CIP, require baselines of installed software, updates, and open ports to be captured and reported against.
Any Compliance Auditor is going to ask to see evidence that a full audit trail of user and device activity is retained, requiring all audit log events to be securely backed up to a central log server.
NNT Change Tracker Gen 7 has been designed to be simple to set-up and use. This is a key differentiator from the more cumbersome legacy products such as Tripwire® Enterprise with complex combinations of Tasks, Actions, Rules and Policies all with regular expression pattern matches to configure.
As we have mentioned in previous Tips and Tricks, here at NNT we are big fans of system hardening, the science of rendering servers, database systems, firewalls, EPOS systems and all other IT devices fundamentally secure.
Network-accessible IT systems are all potentially vulnerable to tampering and cyber attack.
We often find when monitoring communication equipment, that there is a need to exclude lines from the gathered configuration that would cause false positives if left.
As Change Tracker users you’ll be familiar with the automated process used for on-boarding devices. Namely, when a new device registers, it is placed into a grouping structure based on the detected operating system.
When reviewing file integrity changes with Change Tracker, you’ll have undoubtedly noticed the hash value within the events.
NNT provides a Ransomware Mitigation Kit, comprising the necessary automated vulnerability checks and also the Group Policy/Puppet templates to automatically fix any weaknesses identified.
System Hardening / Vulnerability Management – the science of rendering servers, database systems, firewalls, EPOS systems and all other IT devices fundamentally secure is still the most effective - but often the most neglected - security best practice.
We’ve all been there, a patch run has been kicked off and the associated Change Tracker Planned Change was not configured – disaster, and possibly a couple of hundred thousand unplanned changes to boot!
As users of NNT Change Tracker, we know the benefits of Windows File Integrity Monitoring, namely associating a user account with identified file changes, but there is additional value in also understanding at a granular level what specifically changed within the file including the actual line in and to what?
A hardened server is a happy server! NNT maximizes the use of compliance reports with a partnership from the Center for Internet Security (CIS). NNT’s compliance reporting provides you with the tools you need to ensure a hardened build standard across your entire IT environment...
