The most common and costly security risks include the following: What are the different types of security risks? IoT-based Attacks – Security flaws in everything from smart home and mobile devices to industrial sensors to medical technologies are opening up broad new avenues for attackers to find a way into your network and gain unauthorized access to your sensitive information.Cellular networks are increasingly using nearby Wi-Fi networks to offload data traffic, so as 5G and other wireless services grow, the risk of an associated exploit grows accordingly. Wireless threats – Wi-Fi networks are notorious for their general insecurity.Malware-infected apps and phishing attempts can be delivered via text message, voice call or other means. Mobile attacks – Similar to cloud threats, the broad shift from PCs to mobile computing has opened a door for attackers who may be much less on guard against threats when using their phone instead of their computer.Ransomware has been on the rise for years. Ransomware – A type of cybercrime that can infect a system or a network, in which cyber attackers encrypt files on the host then demand payment (usually in untraceable Bitcoin) in exchange for the decryption key.Cloud-based threats – The growth of cloud computing has made this a rich target for cybercriminals who look for ways to infiltrate corporate networks or hijack user endpoints or SaaS services for their own workloads (such as cryptocurrency mining).Armed with your password, the attacker can then drain your bank accounts or cause other types of havoc. Phishing attacks – Still one of the most prevalent types of cybersecurity attacks, these social engineering schemes allow perpetrators to masquerade as someone else - often a financial institution or another service provider - in the hopes of separating you from your login credentials.The modern cybersecurity threat landscape includes dozens of common threats. Today, some of the biggest assaults range from extremely sophisticated and targeted to relatively blunt attacks that take a shotgun-like en masse approach in the hopes of reaching a victim. What are some of the biggest modern cybersecurity threats? Tactics such as zero trust security take the firewall concept even further, presuming that all traffic, whether it originates outside or inside the network perimeter, is inherently dangerous and must be verified before it is allowed. Tools that scan the network and identify problems before an attack occurs are also commonplace in the enterprise. Rather than monitoring data traffic for specific snippets of known bad code (known as “signatures”), security tools use a range of detection techniques, proactively watching for suspicious behaviors, and using technologies such as artificial intelligence (AI) and machine learning to predict whether a certain activity is likely to be malicious. To mitigate these threats, computer security has evolved in a myriad of ways. In one proof-of-concept hack, attackers hacked a refrigerator to reveal a user’s Gmail login credentials. In addition to PCs, attackers target file servers, cloud services, and non-traditional computing devices such as security cameras and video doorbells, thermostats and even light bulbs. Malware that runs cryptocurrency mining software while the victim is unaware is one of the most common types of exploits in use today. These attacks have evolved in recent years to become much more nefarious, turning PCs into “zombie” members of a distributed-denial-of-service (DDoS) botnet, encrypting files to demand a cash ransom from the victim in exchange for the keys to decrypt them, and installing surreptitious software on victims’ machines. Over time, attackers became more sophisticated, and their malware evolved from tools that had once been designed to be little more than a nuisance, to code snippets that could cause real damage by deleting files or corrupting software. And by 2008, those numbers had skyrocketed, with Symantec reporting that that number had topped 1 million. By 2000, there were more than 50,000 computer viruses in the wild. ![]() By the 1980s and 1990s, these types of attacks had become extremely commonplace, to the point where desktop security software (such as Norton AntiVirus and McAfee VirusScan) became essential to stave off attacks arriving via removable floppy disks and, later, through electronic messages and web browsing. The original principles were built around discovering specific attacks - including viruses, worms or other primitive types of malware - and developing tools to stop them. Cybersecurity emerged and gained momentum in the 1970s.
