Sans Institute security group was recently quoted as saying: To right the wrongs in PC security, write the right code. The security group claims to have detected that three common programming errors are the cause of over 85 per cent of serious software vulnerabilities, which open the door to worms and spyware. With the aim of getting to the origin of the problem, quite a few tech companies are giving a push to a Sans attempt to test how firmly designers put in writing their code. In an interview to IBD, Alan Paller, Sans research director maintained that they are making an attempt to get up the nose of the problem at the core, instead of being knee-jerk always. Her further added that the people who are supposed to put code in writing could do with thoroughly reducing the digits of errors. Programmers frequently are shaken to detect their code is in-cluded with security-compromising mistakes. That is to say, usually they are not told about how to put secure code in writing a few instruction manuals followed by them are full of vulnerabilities.
