The NCSC defines a cyber incident as a breach of a system's security policy in order to affect its integrity or availability and/or the unauthorised access or attempted access to a system or systems; in line with the Computer Misuse Act (1990)

10 incident in yr co:

1. Unauthorized attempts to access systems or data
To prevent a threat actor from gaining access to systems or data using an authorized user's account, 2f- This requires a user to provide a second piece of identifying information in addition to a password. Additionally, encrypt sensitive corporate data at rest or as it travels over a network using suitable software or hardware technology. That way, attackers won't be able to access confidential data.

2. Privilege escalation attack
An attacker who attempts to gain unauthorized access to an organization's network may then try to obtain higher-level privileges using what's known as a privilege escalation exploit. Successful privilege escalation attacks grant threat actors privileges that normal users don't have.
Typically, privilege escalation occurs when the threat actor takes advantage of a bug, configuration oversight and programming errors, or any vulnerability in an application or system to gain elevated access to protected data.
This usually occurs after a hacker has already compromised a network by gaining access to a low-level user account and is looking to gain higher-level privileges -- i.e., full access to an enterprise's IT system -- either to study the system further or perform an attack.
To decrease the risk of privilege escalation, organizations should look for and remediate security weak spots in their IT environments on a regular basis. They should also follow the principle of least privilege -- that is, limit the access rights for users to the bare minimum permissions they need to do their jobs -- and implement security monitoring. Organizations should also evaluate the risks to their sensitive data and take the necessary steps to secure that data.

3. Insider threat
This is a malicious or accidental threat to an organization's security or data typically attributed to employees, former employees or third parties, including contractors, temporary workers or customers.
To detect and prevent insider threats, implement spyware scanning programs, antivirus programs, firewalls and a rigorous data backup and archiving routine. In addition, train employees and contractors on security awareness before allowing them to access the corporate network. Implement employee monitoring software to reduce the risk of data breaches and the theft of intellectual property by identifying careless, disgruntled or malicious insiders.

4. Phishing attack
In a Phishing attack, an attacker masquerades as a reputable entity or person in an email or other communication channel. The attacker uses phishing emails to distribute malicious links or attachments that can perform a variety of functions, including extracting login credentials or account information from victims. A more targeted type of phishing attack known as spear phishing occurs when the attacker invests time researching the victim to pull off an even more successful attack.
Effective defense against phishing attacks start awareness to identify phishing messages. In addition, a gateway email filter can trap many mass-targeted phishing emails and reduce the number of phishing emails that reach users' inboxes.

5. Malware attack
This is a broad term for different types of malware that are installed on an enterprise's system. Malware includes Trojans, worms, ransomware, adware, spyware and various types of viruses. Some malware is inadvertently installed when an employee clicks on an ad, visits an infected website or installs freeware or other software.
Signs of malware include unusual system activity, such as a sudden loss of disk space; unusually slow speeds; repeated crashes or freezes; an increase in unwanted internet activity; and pop-up advertisements.
