The Top 5 Vulnerabilities in Computer Security

 Computer security flaws can be classified into a variety of categories based on factors such as where they occur, what created them, and how they could be exploited. The following are some broad categories of vulnerability types:

1. Vulnerabilities in the Network: These are flaws in a network's hardware or software that make it vulnerable to outside infiltration. Wi-Fi access points that aren't secure and firewalls that aren't configured properly are two examples.
2. Vulnerabilities in Humans. The human element is the weakest link in many cybersecurity architectures. User errors can readily expose sensitive data, provide attackers with exploitable entry points, or cause systems to malfunction.
3. Vulnerabilities in the Operating System: These are flaws in an operating system that hackers can use to obtain access to an asset that the OS is installed on—or to do damage. Default superuser accounts, which may exist in some OS installations, and hidden backdoor applications are two examples.
4. Vulnerabilities in the Process: Specific process controls can cause some vulnerabilities (or a lack thereof). The usage of weak passwords is one example (which may also fall under human vulnerabilities).

A few specific examples of security vulnerabilities

1. Superuser or Admin Account Privileges: Limiting program users' access privileges is one of the most basic tenets of mitigating software vulnerabilities. The less information/resources a user has access to, the less damage their account may cause if it is hacked. Many businesses, on the other hand, fail to regulate user account access privileges, allowing almost any user on the network to have administrator-level access. Unprivileged users can create admin-level user accounts due to flaws in some computer security configurations.
2. Hidden Backdoor Programs: When a backdoor program is installed into computers without the user’s knowledge, it can be called a hidden backdoor program. Hidden backdoors are an enormous software vulnerability because they make it all too easy for someone with knowledge of the backdoor to illicitly access the affected computer system and any network it is connected to.
3. Automated Running of Scripts without Malware/Virus Checks: This is one of the most common network security vulnerability that some attackers learned to exploit is the use of certain web browsers (such as Safari) tendencies to automatically run “trusted” or “safe” scripts. By mimicking a trusted piece of code and tricking the browser, cybercriminals could get the browser software to run malware without the knowledge or input of the user.
4. Unknown Security Bugs in Software or Programming Interfaces: Programming bugs and unanticipated code interactions rank among the most common computer security vulnerabilities—and cybercriminals work daily to discover and abuse them. Unfortunately, predicting the creation of these computer system vulnerabilities is nearly impossible because there are virtually no limits to the combinations of software that might be found on a single computer, let alone an entire network.
5. Unencrypted Data on the Network:  Unencrypted data on the network can be a severe risk for organizations of all sizes. Although encryption won’t stop an attack, it can deny attackers the ability to put stolen information to use—rendering it into unintelligible gibberish until it can be decoded. This buys time for consumer protection teams to notify affected parties so they can take identity theft countermeasures to avoid harm.
