Security vulnerability

Internet technology and software are inherently vulnerable due to flaws, weaknesses, and gaps in their design, implementation, and security protocols. Thousands of vulnerabilities exist in both software and hardware that can be exploited by hackers if not properly addressed. Common sources of vulnerabilities include design flaws, poor security management, incorrect implementation, vulnerabilities in operating systems, applications, protocols, and ports. Ensuring systems are properly configured, passwords are strong, and users are educated can help reduce vulnerabilities, but due to the complexity of software it is impossible to have fully secure systems.

security vulnerabilities Ahmed shamel noori
Vulnerability • A flaw or weakness in system security (procedures, design, implementation, or internal controls) that may result in a security breach or a violation of the system's security policy. Briefly vulnerability Is a point where a system is susceptible to attack.
• Internet technology has been and continues to be vulnerable. There have been reports of all sorts of loop holes, weaknesses, and gaping holes in both software and hardware technologies. • No one knows how many of these vulnerabilities there are both in software and hardware. The assumption is that there are thousands. As history has shown us, a few are always discovered every day by hackers . Internet Technology Vulnerability
• Although the list spans both hardware and software, the problem is more prevalent with software. In fact software vulnerabilities can be put into four categories: Operating system vulnerabilities . Port-based vulnerabilities (Enhance system security by blocking those known ports at the firewall).  Application software based errors .  System protocol software such as client and server browser .
• The most frequently mentioned sources of security vulnerability problems in computer networks are : • design flaws, • poor security management, • incorrect implementation, • Internet technology vulnerability, • the difficulty of fixing vulnerable systems, • social Engineering
• Where do vulnerabilities come from? • Flaws in software . • Faulty configuration . • Weak passwords . • Human error .
Vulnerabilities in Systems • System vulnerabilities are weaknesses in the software or hardware on a server or a client that can be exploited by a determined intruder to gain access to or shut down a network.
• How do viruses, rootkits enter a system? • Even without the user doing something “stupid” . • There are vulnerabilities in most software systems . • Buffer Overflow is the most dangerous and common one .
If you remember only one thing from this course: A vulnerability that is will be found “too complicated for anyone to ever find”!
