How a Firewall Provide Protection to your Database?

The biggest threat to an organization is organization itself. Since the organization believes that they are secure enough, they put no efforts in protecting their database. Public and private companies need multiple layers of security. Not only do they need security on their network, but also need different security layers around their most relevant databases and servers. Around-the-clock human monitoring is also required, but most of them do not have these monitoring techniques. Threat actors are 24×7 after you. They don’t stop even when you’re sleeping. Hackers keep a constant eye on an organization, and when they found the network is much available, they secretly enter and leave behind the malware. And the worst thing is that hackers hide the malware in such a way that even an IT specialist finds it difficult to track and overcome the effect of the malware once found.

Database Firewalls are basically a type of Web Application that monitors databases to identify and protect them from attacks to the information stored in it. Not just this, Database Firewalls also enables monitoring and auditing of all access to databases through the logs maintained by them. Also, a database firewall generates compliance reports for regulations like PCI, SOX, etc. Since all the attacks on the databases may not be familiar. So, Database Firewalls build a white list of approved SQL commands that are safe. The white list compares all the input commands entering the database and only those commands that are already present in the white list are sent to the database. Firewalls also maintain a black list of certain specific and potentially harmful SQL statements and do not allow these types of inputs. Database Firewalls also monitor database responses, block potential data leakage and notify the suspicious activities instead of blocking them right away. Attacks like Buffer Overflow and SQL Injection are also blocked by Database Firewalls. Certain Database Firewalls can evaluate factors like IP address, time, location, type of applications, etc. from which the abnormal database access requests arise. So, installing database firewall is necessary for maintaining data security.
