HARDWARE SECURITY - IAS

1. Software Security

2. Hardware Security

Computer security 2 types:

Software security

Is an idea implemented to protect software against malicious attack and other hacker risks so that the software continues to function correctly under such potential risks.

Hardware security

Is vulnerability protection that comes in the form of a physical device rather than software that is installed on the hardware of a computer system.

Hardware

Refers to the physical artifacts of a technology. It may also mean the physical components of a computer system, in the form of computer hardware

1. Motherboard

2. CPU

3. RAM

4. ROM

5. Power Supply

6. Removable media devices

7. Internal Storage

8. Networking

What are the typical PC Hardware?

Hardware Security

A physical device that provides layer of security

1. Modern security work is largely focused on either protecting or attacking target operating systems.

2. Software is not enough to fully protect a system. Security in hardware offers performance and power consumption advantages over its software equivalents.

3. Increasing amounts of data being processed and the complexity of encryption algorithms slows down security implementations severely.

4. Often times these same encryption algorithms can be implemented in hardware.

Why do we need Hardware Security?

1. Implements encryption algorithms to secure data. Store encrypted data in a difficult to access fashion.

2. Prevents unencrypted data from existing in an idle state on the system. In the US, Hardware security conforms to the Federal Information Processing Standards (FIPS).

3. Provides life to the system so that software used on it can be saved for larger time.

What does hardware security do?

1. Insider Attack

2. Invasive Attack

3. Semi-Invasive Attack

4. Non-Invasive Attacks

Types of Attacks:

1. Cryptoprocessor

2. Power protection

3. Heat maintenance

4. Hardware security module

Types of Hardware Security:

Cryptoprocessor

Is a dedicated

computer-on-a-chip or microprocessor for carrying out cryptographic operations, embedded in a packaging with multiple physical security measures, which give it a degree of tamper resistance.

Power protection

A computer requires steady voltage of 110V or 220V. The fluctuations in electric voliage or feq.ent power failure can damage computer hardwire

1. UPS

2. Volt Guard

3. Spike Guard

What are the Power protection devices?

Heat maintenance

We should maintain suitable temperature, moisture and circulation of air in the computer system. Fluctuations in temperature in computer may cause unexpected crashes. There should be proper air condition to maintain suitable temperature in the computer system. Heat can break down contracts or junctions with the chip or other devices.

Hard Security Module (HSM)

Is a physical computing device that safeguards and manages digital keys, performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. These modules traditionally come in the form of a plug-in card or an external device that attaches directly to a computer or network server. A hardware security module contains one or more secure cryptoprocessor chips.
