Common cybersecurity threats and their solutions

The most common cybersecurity threats Today they still present the highest amount of combined risk, but there are dozens of different types of cybersecurity threats, with several new ones added each year, attacking different surfaces, on different platforms again using different attack vectors.

Cyberattacks disrupt millions of businesses around the world and, on average, there is a cyberattack every ten seconds. According to Cisco, “Cyberattacks affect businesses every day. Former Cisco CEO John Chambers once said, “There are two types of companies: those that have been hacked and those that do not yet know they have been hacked.” According to the Cisco Annual Cybersecurity Report, the total volume of events has almost quadrupled between January 2016 and October 2017. “Every year, cybercrime has risen steadily. A typical example of a popular but devastating cyber attack would be ransomware attacks that have caused immeasurable damage to systems around the world. Research shows that cyberattacks cause 53% of cyberattacks cause at least $ 500,000 in damage. The FBI definition of cyber threats is as follows: “The Malicious cyber activity threatens the safety of the public and our national and economic security. The FBI’s cyber strategy is to impose risks and consequences on cyber adversaries. Our goal is to change the behavior of criminals and nation-states who believe they can compromise the US networks, Stealing financial and intellectual property and putting critical infrastructure at risk s in taking risks themselves. To do this, we use our unique combination of authorities, capabilities, and partnerships to impose consequences against our cyber adversaries. “Cybersecurity protects us against various types of malware and attacks, such as ransomware, spyware, worms, and viruses.

What is cybersecurity?

Cybersecurity is the protection of any system, network or digital device against cyber risk. This means protecting systems from the threats of cybercriminals. The NIST CSRC definition of cybersecurity is as follows; “Damage prevention, protection and restoration of computers, electronic communications systems, electronic communications services, cable communications and electronic communications, including the information contained therein, to ensure their availability, integrity, authentication, confidentiality and non-repudiation.” Cybersecurity protects against the most common types of cyber attacks; such as spyware, ransomware, worms, and viruses. Such malware (or malicious software) can take an entire system hostage, install malicious software, spy on and monitor user data, and even disrupt hardware components. Cybersecurity includes tools such as antivirus, VPN or virtual private networks, firewalls, routers.

What is a cybersecurity threat?

A cybersecurity threat directly refers to a malicious or malicious attack by an individual or organization. The individual or organization that is attempting the malicious attack, is after violating, disrupting or in some way shaping or shaping, gaining access to a certain target network. The end goal is usually espionage, data corruption, data theft, etc. There is absolutely no cyber defense that can guarantee a 100% cyber crime free scenario. Cyber ​​threats are becoming increasingly sophisticated, and high-level APT attacks domestically for political reasons are on the rise (mainly the attacks take place between the US, Russia and China.

Type of cyber threats and sub-threats

There are several main types of threat categories, as well as sub-threats;

  1. Malicious software
  2. Spear phishing and phishing
  3. Other attacks

In the category of malware, the following types are included; ransomware, spyware, back doors, trojans, viruses and worms. When it comes to spear phishing and phishing, this is a common type of scam or fraud that does not use malware, but uses social engineering to trick the user into entering their credentials in a fake message, login, app, or web page. . Other types of attacks used by cybercriminals are Man-in-the-Middle or MITM attacks when malicious actors get in between a two-way communication. In addition, there is the famous DDoS or distributed denial of service attack that brute forces hundreds or thousands of access attempts to slow down, interrupt and cause downtime on a website. There are also more types of attacks that can ring a bell, such as SQL (structured query language) that relies on malicious scripts and Domain Name System (DNS) attacks that exploit vulnerabilities in the DNS system.

Where do cyber threats come from?

Cyber ​​threats come from various sources, which vary widely in severity. They can come from; Nation-states (most often Russia and China), organized criminal groups, individual blackhat hackers, terrorist groups, and malicious insiders (insider threats). The industry also expects several emerging threats on the horizon, such as pandemic-related attacks (supply chain and others, for example), cloud breaches (due to the heavy global reliance on cloud storage), IoT or attacks from Internet of things (smart connected devices) and many more. Cyber ​​threats are now recognized as the number one global threat by both industry IT leaders and senior global insurance companies. Not only that, but billions of dollars are being invested in the industry to prevent future attacks like the 2020 SolarWinds Orion cyberattack that nearly cost the US its national security. In the future, we can look forward to quantum technology in the fight against cybercrime and privacy crimes. Quantum technology will usher in a new level of encryption technology that (unless the bad guys take advantage of it anyway) will stop traditional cybercrime and reduce global cyber threats. How else do we solve the problem of cyber threats? The economy must come together in a unified cyber readiness plan, policies must be kept in check, and we must make the most of existing and emerging technologies. Beyond this, paradigms like Zero-Trust models, proper employee training, and the use of artificial intelligence in managed security solutions are what most organizations will want to survive. It doesn’t seem like nation-state-level attacks are going to stop anytime soon, especially since every country in the world stores a lot of sensitive information in the cloud (making it like a honeypot for cybercriminals). The only way to stop nation-state attacks in their tracks is (like the US Executive Order) to create new regulations for cybersecurity at the national level that allow public and private collaboration to stop cybercrime.
