How secure is your Wi-Fi network? The Mayans’ Best Guide To Secure Access Service Edge tells you how safe to share passwords or credit card information over the Internet?
Best Guide To Secure Access Service Edge
Intrusion prevention is an important part of a Security Administrator’s job. Intrusion prevention is the first line of defense against intruders trying to gain access to your local area network. Also, Intrusion prevention systems (IPS) use a combination of technologies to help prevent unauthorized access to your network.
One key component of an intrusion prevention system is signature-based detection. It uses signatures to detect known malicious activity. An intrusion prevention system, or IPS, is a hardware or software system that detects a malicious attack. This takes steps to block it from your network.
When an intrusion occurs, an intrusion detection system watches all the devices on your network for suspicious activity. When it detects something suspicious, such as someone trying to break into one of your computers. It takes action to block the attack and prevent it from reaching its intended target.
This helps prevent damage and data loss from security breaches. In addition to signature-based detection, which helps protect against known threats, many intrusion prevention systems offer proactive protection features. This attempt to identify new security threats before they have been categorized by IDS signatures.
These proactive features include anomaly detection and behavior-based detection.
Anomaly vs Behavior-based Detection
Anomaly detection looks for things that don’t fit normal traffic patterns on your network. This is such as a user who logs in from India but normally logs in from New York City. Also, a user who always enters her password at the same time every day but today tries to log in at 3:00 a.m.
Then again log in at 6:00 p.m. When she never logs in at those times of the day. Anomaly detection can help identify new types of attacks and can be useful when hackers change their methods.
For example, if they begin using new attack tools or if they launch a denial-of-service attack instead of trying to steal data via an SQL injection attack. Behavior-based detection monitors users’ actions on your network. This is by looking at their login behaviors and other actions such as how often they connect from different IP addresses.
Also, how much data they transfer every day on average raises an alert if any unusual behavior occurs. These are such as if a user suddenly transfers 2 gigabytes of files in one session or connects from many different IP addresses in one day. Behavior-based detection can be very useful in detecting advanced persistent threat (APT) attacks.
Summary
A type of sophisticated hack that’s used by organized crime groups, government agencies, and nation-states. This is to target specific people or organizations. Because APTs often follow a specific pattern. An intrusion prevention system can also use contextual data.
This is such as information from an antivirus program or user-behavior analytics, to help it detect more sophisticated threats. Firewalls are a good step toward Internet security. But they do not completely secure your network.
For example, you may have a firewall for your Internet connection. But if you connect to the Internet through a dial-up modem on your home computer, there is no firewall between you and the Internet.
