Almost all applications today have built-in security features. However, you still cannot rely 100 percent from such security features as hackers normally find ways to breach built-in protective measures. Such threats are very common especially for web based applications. These applications are frequently queried by legitimate users but they are also exposed to attacks by those who may want to penetrate your network server or disrupt your service. That is why application security appliance as well as Spam filters should become integral component of your network’s entire security countermeasures. There are many ways how your web applications can be attacked by hackers and spammers. For example, hackers can perform SQL injection, modify cookie values, and tamper your web forms to conduct phishing operations. Some elements can also bombard your servers with malicious queries that can cause system and network crashes. Such denial of service attack can become a huge headache and you can lose potential customers if it goes unchecked. By implementing application security appliance over your network, you will be able to plug the vulnerabilities of your applications and prevent such attacks from happening. On the other hand, Internet spam filters systems can protect your network from virus intrusions. Traditionally, the most common response to security threats is to build firewalls around your web applications and servers. These firewalls can be effective for a while but may not be able to prevent sophisticated and sustained attacks. So you should implement other measures such as requiring legitimate users to authenticate their sessions within your local network and whenever they use web applications. You also need to strengthen Spam filters with mail security appliance that will block incoming mails with malicious signatures. And as added countermeasure, you should also implement anti-penetration application security hardware that will constantly scan network traffic. Aside from deploying application security and spam filters appliance over your network, the critical information about your servers should also remain private. Keeping a low profile for your servers can be very helpful in evading the reconnaissance activities of hackers. What you can do is to remove personal or corporate information from your who-is records and hide the engineering profile of your servers. The operating system as well as the database build of your servers should remain private. Hackers can exploit such information and device ways to penetrate your system. You must also avoid exposing sensitive database directories by excluding them from your robots.txt file. Hackers may use automated robots to access server information. So if critical directories are not included in robots.txt, then these areas in your servers will not be accessible. Protecting your web applications is very important. It is very costly for your company if the security of your networks and applications will be compromised. The good thing is there are many ways to protect your network from hacking. And the best countermeasure that you can do is to deploy anti-penetration security appliance for your network and effective spam filters for your mail servers. These systems will effectively prevent hackers from attacking your network.
