What is Managed Security?

Security of IT network is not just about stopping viruses, keeping hackers out and putting a lid on spam email. Information security is also about working with employees and management to make sure that everyone is aware of current threats and how they can protect their information and systems.

The terms information security, computer security and network security are frequently used interchangeably. These fields are interrelated often and share the common goals of protecting the confidentiality, integrity and availability of information; however, there are some subtle differences between them. Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction. Computer security is the generic name for the collection of tools designed to protect the processed and stored data and to thwart hackers.

Network security is the generic name for the collection of tools designed to protect data during their transmission. In connection with the Internet, the term internet security is often used. Moreover, this term involves the concept of parametric security which is the generic name for the collection of tools designed to protect the resources of a private network from users from other networks. The differences among information security, computer security and network security lie primarily in the approach to the subject, the methodologies used and the areas of concentration.

Information security is concerned with confidentiality, integrity and availability of data, regardless of the form the data may take: electronic, print, or other forms. Computer security can focus on ensuring the availability and correct operation of a computer system without concern for the information stored or processed by the computer. Network security focuses on protecting data during their transmission. The insecurity of computer systems and networks goes much further than the well-known computer viruses, and has now become a significant challenge to overcome. In the networked world, the new generation of miscreants and those who steal data do not need to have physical contact with the victim. Data can be easily copied, transmitted, modified or destroyed. As a result, there are no traces left, identification and apprehension of the culprits is nearly impossible, and the legal framework does not make adequate provision for justice in this kind of crime. Every technology has some known or unknown inherent weaknesses, or vulnerabilities that can be exploited by a sufficiently motivated miscreant. Some weaknesses are publicized widely in the media because they are associated with well-known products or companies. There are other vulnerabilities, we may not know about yet.

Internet protocols were not designed for security. Today, security best practices, security services, and an array of products from many vendors work together to reduce the risks inherent in the environment. A service provider with adequate expertise and experience can help in tackling the overall data security issue and reduce the risks for an organization by working in conjunction with its internal teams.
