Different types of security used for a network

Various wireless security protocols were developed to protect home wireless networks. These wireless security protocols include WEP, WPA, and WPA2, each with their own strengths and weaknesses. In addition to stopping uninvited guests from connecting to your wireless network, wireless security protocols code your private data as it’s being transmitted over the airwaves.

Data Security

Data security refers to protective digital privacy measures that are used to prevent unauthorized access to computers, databases and websites. Data security also protects data from corruption.

Examples of Data security

•software/hardware disk encryption backups

•data masking  

•data erasure.

Access security

Access control is a security technique that can be used to regulate who or what can view or use resources in a computing environment. There are two main types of access control: physical and logical. Physical access control limits access to campuses, buildings, rooms and physical IT assets. Logical access limits connections to computer networks, system files and data.

Examples of access security

There are two main types of access control:

•Physical – like passwords

•Logical – like access rights

•

The four main categories of access control are:

•Mandatory access control

•Discretionary access control

•Role-based access control

•Rule-based access control

Physical Security

Physical security is the protection of personnel, hardware, programs, networks, and data from physical circumstances and events that could cause loss or damage to an enterprise, agency, or institution. This includes protection from fire, natural disasters, burglary, theft, vandalism, and terrorism.

Examples of physical security

Physical measures:

•Locks

•Fences

•Walls

•Safes

Surveillance systems:

•Heat sensors

•Smoke detectors

•Alarms

•Cameras

Methods can be implemented to apprehend attackers and to recover quickly from accidents, fires, or natural disasters.
