Network Security Tools List
In order to fight the potential unauthorized entry of an outside bug into your system, you must know the top seven network security tools that will help you to eradicate the possible threats. Below is the list of the top seven network security tools:
- Nessus: It is a scanner of vulnerability.
- Snort: It detects an incursion in the network.
- BackTrack: This tool is used for the testing of penetration.
- Netcat: It is a tool for the exploration and debugging of the system.
- Aircrack: This tool is the cracker of WPA and WEP.
- Wireshark: The old name of this network security tool is 'Ethereal'. It is used as a packet sniffer.

There are seven different network security techniques to address every situation. These techniques are mentioned below:
- Detection of Anomaly
Whenever there is an entry of an outside anomaly, it is very important to detect it as soon as it gains entry. The engines of network anomaly detection can be used to thoroughly scrutinize the scum which has gained entry into the system and give you enough time to properly respond to it.
- Access Control
If the external bodies are unable to get into the system, all of your data will be saved from the catastrophic damage. However, some accredited users can bring potential destruction to your data. Access control is the kind of network security technique that will limit the access and resources of the users to the concerned individual who's handling all the responsibilities of the given parts of the network.

Moreover, this technique can help limit the damage done to the network by the already existing malware.
- Email Security
Email security is related to the security of human weaknesses. Emails can be used to forge false identities in order to gain potential information regarding the data of the business. The attackers may even download malware into a specific organized and possibly under attack system. With the email security technique, one can identify a false or thereby, treacherous emails and can save vital information regarding his/her business by blocking such threats.
- Data Loss Prevention
The loss of data mainly refers to as human error. As the element of human is considered to be the weakest link in the IT industry, the techniques of data loss prevention are taken into account for the possible misuse of the data by the users or other staff members. These policies and techniques of data loss prevention will not let the users compromise the sensitive data at any cost.
- Firewalls
Firewalls are the protective barriers that are constructed between your internet connection and the network. It works as a semi-permeable sheet that allows only authorized or sanctioned traffic to pass through it while it halts the entry of the rest of the unapproved traffic into your business data.
