Cyber Security Incident Report Pdf

Cyber security professionals continually defend computer systems against different types of cyber threats. Cyber attacks hit businesses and private systems every day, and the variety of attacks has increased quickly. The motives for cyber attacks are many. One is money. Cyber attackers may take a system offline and demand payment to restore its functionality. Ransomware, an attack that requires payment to restore services, is now more sophisticated than ever.

Corporations are vulnerable to cyber attacks, but individuals are targets too, often because they store personal information on their mobile phones and use insecure public networks. Tracking evolving and increasing cyber attacks is key to better cyber security. A cyber security threat refers to any possible malicious attack that seeks to unlawfully access data, disrupt digital operations or damage information.

Cyber threats can originate from various actors, including corporate spies, hacktivists, terrorist groups, hostile nation-states, criminal organizations, lone hackers and disgruntled employees. In recent years, numerous high-profile cyber attacks have resulted in sensitive data being exposed. For example, the Equifax breach compromised the personal data of roughly million consumers, including birth dates, addresses and Social Security numbers. In , Marriott International disclosed that hackers accessed its servers and stole the data of roughly million customers.

Cyber security professionals should have an in-depth understanding of the following types of cyber security threats. Malware is malicious software such as spyware, ransomware, viruses and worms. Malware is activated when a user clicks on a malicious link or attachment, which leads to installing dangerous software. Cisco reports that malware, once activated, can:. Emotet continues to be among the most costly and destructive malware.

Several other techniques may be used, and some cyber attackers use the time that a network is disabled to launch other attacks. A botnet is a type of DDoS in which millions of systems can be infected with malware and controlled by a hacker, according to Jeff Melnick of Netwrix, an information technology security software company.

Botnets are in different geographic locations and hard to trace. A man-in-the-middle MITM attack occurs when hackers insert themselves into a two-party transaction. After interrupting the traffic, they can filter and steal data, according to Cisco. Attackers insert themselves between the visitor and the network, and then use malware to install software and use data maliciously. Phishing attacks use fake communication, such as an email, to trick the receiver into opening it and carrying out the instructions inside, such as providing a credit card number.

When infected, the server releases information. Submitting the malicious code can be as simple as entering it into a vulnerable website search box. With the right password, a cyber attacker has access to a wealth of information. Cyber security practices continue to evolve as the internet and digitally dependent operations develop and change. According to Secureworks, people who study cyber security are turning more of their attention to the two areas in the following sections.

Individual devices that connect to the internet or other networks offer an access point for hackers. Cytelligence reports that in , hackers increasingly targeted smart home and internet of things IoT devices, such as smart TVs, voice assistants, connected baby monitors and cellphones.

Data storage on devices such as laptops and cellphones makes it easier for cyber attackers to find an entry point into a network through a personal device. Consequently, companies and government agencies need maximum cyber security to protect their data and operations. Understanding how to address the latest evolving cyber threats is essential for cyber security professionals.
