Introduction

Software transports instructions to the computer that it follows to operate various functions. Until now, it is not perfectly secure enough to be protected against hackers, attackers, and undesired users etc. Nothing can be done for software to be put in a shell that is impossible to be affected ever. Due to the facts, software security assessment is essential to be taken place so that no effort remains for it is accessible to attackers. Software security assessment helps and guide to identify and prevent software vulnerabilities that harm data and information stored.

Software Vulnerability

Software vulnerability can be described as a weakness through ...

There are three basic aspects that cannot be ignored when addressing digital security. These include computer security principles, encryption and programming techniques used to achieve security. Digital security is all about information and systems security it’s majorly focused on protecting systems and the information they create, process, transmit and store. This clearly brings out the mostly ignored fact that information in motion is prone to attacks and therefore should be protected. Sniffing and snooping of network systems is a bitter reality that cannot be ignored. These are the main attacks that information in motion could be subjected to. In ...
