While protection from virtual attacks remains to be of high priority, it is important to make right
security assessment with the following tools. One should comprehend how
Intrusion Defense or Prevention Systems function to make a right choice.
Intrusion Prevention System (IPS), as well as Firewall, is the tool of control: it monitors a network for malicious activity due to certain rules. When IPS finds ‘dangerous’ packet, it blocks it, if not – allows a traffic through. Thus, the given system sits in-line and works as:
- an indicator of harmful activity
- an alarm and a data logging device
- a blocking tool when an intrusion is detected
- a data leak protection device
In addition to this, an IPS corrects Cyclic Redundancy Check errors, prevents TCP sequencing issues and cleans up problematic traffic.
Another security tool in
computer networking services is
Intrusion Defense System, which functions differently than IPS. It may be considered as “visibility” tool. Sitting off aside of a network, an IDS monitors whole traffic and sends its analysis to
IT support specialist.
The IDS helps to solve the following problems:
- violation of security policy
- elimination of viruses and infections
- defense from information leak (when it happens on purpose or by accident)
- correction of wrong configuration settings of an app or a system (e.g. in case of firewall rules do not match policy)
- a barrier to unauthorized access (users or apps)
