Bangalore Labs provides VPN security to some of its key customers in India like Hathaway and Pidilite Industries.

Intrusion Detection Systems

IDS inspect all inbound and outbound network activity and identifies suspicious patterns that may indicate a network or system attack from someone attempting to break into or compromise a system. An ID differs from a firewall in that a firewall looks out for intrusions in order to stop them from happening. The firewall limits the access between networks in order to prevent intrusion and does not signal an attack from inside the network. IDS evaluates a suspected intrusion once it has taken place and signals an alarm. An IDS also watches for attacks that originate from within a system.

Authentication/Access control

Authentication can be based upon what someone has (a smart card, token, or ID card), what he or she knows (a password or PIN), what he or she is (a biometric like a fingerprint or voiceprint), or any combination of these. Distinction can be made between authentication and authorization; the former deals with validating that users are who they say they are, while the latter deals with validating which specific resources the user has permission to access.

Red Hat Linux (RHL) comes with substantial security features like IP tables that provide authentication and allow administrators to create rules and policies.

RSA Security India has some of the largest MNCs using RSA SecureID in India, including the likes of ABN Amro, HSBC, Citibank, ICICI Bank and Netscape AOL.

Encryption

It is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text; encrypted data is referred to as cipher text. RSA, Symantec and other organizations provide Encryptio solutions.

Technology tools manage various risk factors and prevent security breaches. These tools need to be reviewed periodically, to keep them up-to-date so that they can tackle new security threats.
