Please also the referencing style is Harvard referencing.
DQ1: Encryption Algorithms
3DES is a mode of the DES encryption algorithm that encrypts data not just one, but three times. Three 64-bit keys are utilised by the algorithm; overall, a key length of 192 bits is created!
But even such high security encryption can be cracked; no one has formally ‘proven' that 3-DES or RSA are ‘secure'. Despite a fail-proof warranty, companies trust billions in economic data-wealth behind such security technologies. If a lock has a key, there will always be a way to forge permission for entrance.
In this Discussion, you will weigh in on the security of these popular encryption techniques, and consider which one you would prefer to protect your own data.
To complete this Discussion:
Post: Submit an essay in which you take a stance on the level of security provided by 3DES and RS. Using evidence from the literature, defend your personal stance in believing 3DES and RSA are (or are not) secure technologies. Imagine you are a network professional responsible for securing private financial data worth $3M on the analytics market. Choose and defend one of the two security technologies (you may also introduce a third example).
DQ2:: IPsec and the Network Layer
123456, password, admin, princess...
-from SplashData's ‘Worst Passwords of 2013'
Names of Web sites, applications and common keystrokes make poor security passwords. Despite security advocates call to consumers to employ security best practices, computer users continue to employ weak passwords.
Similarly, security network professionals must cautiously assume how their network users will behave. For example, a common assumption is that malicious intruders only originate from outside the company. Such a belief can lead to enforcing security measures on the virtual ‘perimeter walls' of a company. However, employees or contractors can inflict misguided damage and steal information from inside the network.
In this Discussion, you will explore IPsec, the most common network-layer security protocol, and consider what additional security measured might be needed beyond IPsec.
To complete this Discussion:
Post: Submit an essay in which you share and value your own research findings on IPSec. Describe and analyse situations that require security mechanisms at layers above IP, despite the security provided by IPsec. List the roles of the application layer as it operates in the overall security scheme of the network.
