There are many tools for increasing information security, including software that scans for computer viruses or prevents unauthorized intrusions into computer system. The first and most simple to use are having a password. Having a password by itself is not capable of providing a high level of security for multiple users. The foundation of this knowledge is held within an information security masters degree!

The next tool to talk about is Cryptography. This arguably is the best tool for information security.Cryptography is the process by which raw message information (plaintext) is mapped or encrypted to a scrambled form (cipher text) before transmission or storage, then mapped back to its original form again (decrypted) when an authorized party wishes to read the plaintext.
Cryptography has the disadvantages of added complexity, higher cost, and system slowdown.
The next tool to talk about is Defense in depth. This tool helps you protect network resources even if one of the security layers is compromised. After all, no single security component can be guaranteed to withstand every attack it might need to face.
What exactly does defense in depth entail? The simple answer is the perimeter, the internal network, and a human factor. Each of these comprises many components, which are independently not enough to secure a network. The key lies in each component complementing the others to form a complete security picture. The extent to which you need to apply network security layers depends on the needs and capabilities of your business.
The next tool is firewalls there are too many to comment on but here are a few. First let’s talk about Proxy Firewalls. Proxy Firewalls are the most advanced and least common type of firewall. Proxy firewalls are also stateful, in that they block any nonestablished, nonpermitted connections.Proxy firewalls offer a high level of security because internal and external hosts never communicate directly.Using proxy firewalls reduces the possibility of malicious traffic entering or exiting your network by ensuring that only protocol-compliant traffic passes through.
Stateful Firewalls are able to recognize and block traffic that is part of a nonestablished, nonpermitted connection, such as attempts at reconnaissance. Stateful firewalls a valuable part of defense in depth by adding another layer of security to your network.
Host-centric (personal) firewalls are generally implemented as software modules that run on individual machines, screening network traffic as it enters and leaves the system.Personal firewalls help defense in depth by strengthening the perimeter on every host.
The Internet is an open zone where anyone can create a website that may place malware on your computer or server. This is also the space that gives shelter to people who are on the prowl to reach your computer or servers to access your data for misuse. No matter what tool you use to protect your information make sure you test it periodically to make sure it’s in proper working condition. As you can see, it is very valuable that you obtain a masters degree in information security today.
