Security in Computing

Product Information

These weaknesses included replay attacks and a vulnerability that allowed hackers to alter unencrypted communications sent by users. Several computer security consulting firms produce estimates of total worldwide losses attributable to virus and worm attacks and to hostile digital acts in general. While not cybersecurity technology per se, disaster recovery capabilities often play a key role in maintaining business continuity in the event of a cyberattack. Combination SIM/DVD devices are being developed through Smart Video Card technology which embeds a DVD-compliant optical disc into the card body of a regular SIM card.

Medical devices have either been successfully attacked or had potentially deadly vulnerabilities demonstrated, including both in-hospital diagnostic equipment [99] and implanted devices including pacemakers [100] and insulin pumps.Cybercriminals are finding new attack vectors all the time—including Linux systems, operational technology (OT), Internet of Things (IoT) devices, and cloud environments.

If you are attacked, immediately inform the cyber cell so that they may take appropriate action and also protect others from getting attacked by the same person. Surfacing in 2017, a new class of multi-vector, [21] polymorphic [22] cyber threats combined several types of attacks and changed form to avoid cybersecurity controls as they spread. Denial of service attacks (DoS) are designed to make a machine or network resource unavailable to its intended users.Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, elections, and finance.

However, relatively few organizations maintain computer systems with effective detection systems, and fewer still have organized response mechanisms in place. Infected USB dongles connected to a network from a computer inside the firewall are considered by the magazine Network World as the most common hardware threat facing computer networks.A physical example would be, suppose if you are talking to another person of your organization and if a third person listens to your private talks then he/ she is said to eavesdrop on your conversation. While hardware may be a source of insecurity, such as with microchip vulnerabilities maliciously introduced during the manufacturing process, [141] [142] hardware-based or assisted computer security also offers an alternative to software-only computer security. Eavesdropping: Eavesdropping refers to secretly listening to someone’s talk without their permission or knowledge. Forward web proxy solutions can prevent the client to visit malicious web pages and inspect the content before downloading to the client machines.
