What Is Vulnerability And How To Keep It From Cyber Criminals
What Is Vulnerability
What is vulnerability and why are they important in network security? In network security, vulnerability is a fundamental weakness that can be exploited by an external threat actor, like an attacker, to penetrate network privileges. To attack a particular vulnerability, an external attacker would need to have at least one relevant tool or technique to link to the system vulnerability. For instance, a remote user with permission to browse the control panel, can use a ‘file’ to upload a malicious program to the victim machine. With the help of the exploit code, he could gain access to all system resources and execute any malicious program he likes. The whole method is done without the knowledge of the victim application or service, leaving all users open to attacks.
Vulnerability definition in IT department is very vague and is used broadly to describe any type of vulnerability that can be exploited for cyber attacks. The classification also depends on whether the vulnerability is considered to be critical, medium or non critical. Critical vulnerabilities are often used to develop software that can defend against cyber attacks. Medium level vulnerabilities can allow an intruder to execute some secret codes or execute some DLL (directly installed Dynamic Link Library) that is loaded by default by the operating system. Non critical vulnerabilities are those that allow attackers to do something but do not disclose the details. Both of these levels require a coordinated and well-defined security policy to keep security at risk.
There are various ways to locate vulnerabilities. The most commonly used method is to search the vulnerable machines on the Internet to find misconfiguration events. It is also possible to search the machine for vulnerability databases. Some companies also scan for misconfigurations manually or have special vulnerability scanners available for this purpose.

While most attacks on network security happen unintentionally it is also possible to be attacked deliberately and that is what makes security breaches such as intrusions, viruses, spam, exploits and even code injection attacks so serious. Intrusion detection systems can provide early alerts on such activities which help network security professionals assess the risk of an attack and respond accordingly. Some of the types of intrusion detection systems include content filtering, email filtering, web filtering, content injection and URL filtering.
A good security posture must constantly monitor for and respond to potential threats. It does not matter how careful you are with your computer settings; if you don’t constantly monitor your network and other applications you will be caught off guard when an attack occurs. Your responsibility includes continuously monitoring your network and application and constantly updating your software and security updates. Security professionals will use the information about what is vulnerability and actively monitor their applications and networks for any signs of threat or deviation from the norm.
It is not enough to rely on security to protect your company from cyber criminals and hackers. Your company must also have a strong defense in place if it wants to defend itself against foreign hackers bent on stealing confidential data and intellectual property. Your business may not have a direct contact with cyber criminals but there are ways to detect the presence of cyber criminals on your system and impede their efforts. A proactive approach to the identification and definition of vulnerabilities in your network and application is what is needed to keep your company protected from cybercriminals who try to use your system for their own purposes.
