Knowing how to identify computer security threats is the first step in protecting computer systems.

Threat (computer)

Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It's also known as information technology security or electronic information security. The term applies in a variety of contexts, from business to mobile computing, and can be divided into a few common categories. A compromised application could provide access to the data its designed to protect. Successful security begins in the design stage, well before a program or device is deployed. The permissions users have when accessing a network and the procedures that determine how and where data may be stored or shared all fall under this umbrella. Disaster recovery policies dictate how the organization restores its operations and information to return to the same operating capacity as before the event.

Cyber threats sometimes feel unrelenting and are becoming more dangerous every day. While the internet presents users with lots of information and services, it also includes several risks. Cyberattacks are increasing in sophistication and volume, with many cybercriminals using a combination of different types of attacks to accomplish a single goal. There are various forms of malware ranging from viruses and worms to Trojans and beyond. Malware is often seen as a catch-all term that refers to any software designed to cause damage to a computer, server, or network. Antivirus software is the most known product to protect your personal devices against malware and is a great start to prevent potential threats. While for enterprises, protecting your endpoint is essential to quickly detect, prevent, and correct advanced threats to your business.

In October a Task Force was organized by the Advanced Research Projects Agency now the Defense Advanced Research Projects Agency to study and recommend appropriate computer security safeguards that would protect classified information in multi-access, resource-sharing computer systems. A slightly modified version of the report — the only omissions were two memoranda of transmittal from the Task Force to the Chairman of the Defense Science Board and onward to the Secretary of Defense — was subsequently published as Rand Report R, Security Controls for Computer Systems. At that time it was felt that because representatives from government agencies participated in the work of the Task Force, the information in the report would appear to be of an official nature, suggestive of the policies and guidelines that would eventually be established. Consequently, it was felt prudent to classify the report Confidential overall. Nearly a decade later the report is still a valuable comprehensive discussion of security controls for resource-sharing computer systems. Ideas first expressed in this report and even occasional figures from it have gradually seeped into the technical literature, but it still contains material that has not been published elsewhere. For example, it includes an appendix that outlines and formally specifies a set of access controls that can accommodate the intricate structure of the classification system used by the defense establishment.
