__Security Controls Flashcards
What are some common types of security controls?
Security controls are measures taken to protect information systems from unauthorized access use
disclosure
disruption
modification or destruction. Common types of security controls include authentication
authorization
encryption
access control lists (ACLs)
firewalls and intrusion detection systems (IDS). These controls help ensure that only authorized users can access sensitive data and that any malicious activity is detected and prevented.
Can you explain the difference between preventive and detective controls?
Preventive controls are measures taken to reduce the risk of a security incident occurring such as implementing access control policies or conducting regular security assessments. Detective controls are measures taken to detect any security incidents that have occurred
such as monitoring network traffic or using intrusion detection systems. Both types of controls are important for maintaining a secure environment.
When would you use access controls
and what types are available?
Access controls are used to limit access to certain resources or information. Common types of access controls include authentication
authorization
and encryption. Authentication is used to verify the identity of a user
authorization is used to determine what level of access a user has
and encryption is used to protect data from unauthorized access.
How can network security controls be used to protect against cyber attacks?
Network security controls can be used to protect against cyber attacks by implementing firewalls antivirus software
and encryption. Firewalls can be used to block malicious traffic from entering the network
while antivirus software can detect and remove malicious files. Encryption can also be used to protect data in transit and at rest
making it more difficult for attackers to access sensitive information.
What are some examples of physical security controls?
Physical security controls are measures taken to protect physical assets from unauthorized access damage
or theft. Examples of physical security controls include locks
fences
alarms
surveillance cameras
and guards. Access control systems can also be used to limit access to certain areas or resources.
How can encryption be used as a security control and when is it necessary?
Encryption is a security control that can be used to protect data from unauthorized access. It is necessary when sensitive information needs to be kept secure
such as passwords
financial records
or confidential documents. Encryption ensures that only those with the correct key can access the data
making it much more difficult for malicious actors to gain access.
What are some common examples of administrative security controls?
Administrative security controls are policies and procedures that help protect an organization’s information assets. Common examples include user access control data classification
incident response plans
and security awareness training. These controls help ensure that only authorized personnel have access to sensitive information and that all personnel are aware of the importance of protecting the organization’s data.
How can you use security controls to protect against social engineering attacks?
Security controls can be used to protect against social engineering attacks by educating employees on the risks of such attacks implementing policies that require authentication for access to sensitive information
and monitoring user activity for suspicious behavior. Additionally
organizations should use strong passwords and two-factor authentication to protect against unauthorized access.
When would you use intrusion detection systems (IDS) as a security control?
Intrusion detection systems (IDS) are an important security control that can be used to detect malicious activity on a network. They monitor network traffic for suspicious activity and alert administrators when they detect something out of the ordinary. This allows organizations to quickly respond to potential threats and take appropriate action to protect their systems. Additionally IDS can be used to identify weak points in a network’s security posture
allowing organizations to take steps to strengthen their defenses.
What types of security controls are most effective against insider threats?
The most effective security controls against insider threats are those that focus on user behavior monitoring access control
and data encryption. User behavior monitoring helps to detect suspicious activity and identify potential malicious actors. Access control ensures that only authorized personnel have access to sensitive data. Finally
data encryption ensures that even if an insider gains access to the data
it is still unreadable without the proper decryption key.
