Information security, or InfoSec, is focused on securing all of an organization’s data, whether it’s digital or analog and wherever it’s stored. In contrast, cybersecurity is about protecting digital data from being compromised or attacked. While there is overlap between the two, they are different, and cybersecurity is often seen as a subset of information security.
The term botnet is an abbreviation of “robotic network” and refers to a collection of computers hijacked by malicious code to carry out scams and cyberattacks. By maliciously leveraging a network of computers, hackers can efficiently carry out more significant attacks. These include DDoS attacks, data theft, malware distribution, and e-mail spam.
An attack surface is all the different points – known or unknown – that an attacker can use to access a system. Attack surfaces are rapidly expanding and include software, operating systems, IoT and mobile devices, data centers, and even people. Understanding the scope and vulnerabilities of your attack surface is a crucial component of cybersecurity
Phishing is a type of cyberattack where a fraudulent email attempts to trick the recipient into revealing sensitive information (such as login credentials) or downloading malware. These emails are usually sent to a large number of people, whereas spear phishing is more targeted to a specific individual. Phishing emails are the most common delivery method for ransomware and a cautionary example of how important the human element can be to cybersecurity.
Spear phishing is a social engineering attack that targets a specific individual by sending them what appears to be legitimate communication from a known and trusted entity. Targets are usually directed to a false website where hackers attempt to steal their identifying information, extort money, or infect their devices with malware. In contrast, phishing casts a broader, less personal net.
Ransomware is a type of malicious software (malware) that uses encryption to deny an organization access to their own files, databases, and applications. A ransom is then demanded to restore access.
In a denial-of-service attack, the hacker attempts to make a system or resource unavailable by stopping or disrupting the services of the host connected to that network. This can cause serious disruption to business operations and could be a distraction for a more serious type of attack such as a ransomware attack.
Cyberwarfare is big business, and the most pervasive hackers are often essentially mercenaries, hired as part of sophisticated and well-funded criminal organizations or adversarial nation-states Whether these organizations aim to extort money or exert political influence, the end result is that some of society’s most critical data is at stake, and some of our most essential services and businesses are continually put at risk. Furthermore, hacking and phishing are not the only means of committing cyber attacks. Companies also have to be on the alert for unethical employees who may be prepared to compromise or sell corporate data for a price. Cybersecurity is as much about managing people as it is about managing technology.
