Flashcards do conjunto (10)
- 1The hardware needed to connect standalone computers into a networkA network adaptor such as a network interface card.
- 2The reason why we need it isThe card will connect your device to a switch, router or a wireless access point.
- 3—......
- 4Star topology how it worksIn a star topology, the nodes connect with each other through a central point. This is so that all of the computer share resources however if the central node fails all of the computer fails.
- 5—.......
- 6Mesh topology how it worksIn a mesh topology, all nodes are connected to each other without needing a central switch. Meaning that if anything fails that the system still works
- 7Different forms of attacksThere are lots of different forms such as
(Worms, DDoS, Trojans, Malware, Viruses, Phishing) and much more. - 8Different threats posed to networks.(malware, phishing
people as the ‘weak point’ in secure systems (social engineering)
brute force attacks
denial of service attacks
data interception and theft
poor network policy) - 9Ways to prevent particular threats*penetration testing
*network policies
*anti-malware software
*firewalls
*user access levels
*passwords
*encryption. - 10Hexadecimals why its better then binaryHexadecimal is much easier to remember and write because each hexadecimal value is equivalent to 4 bits of binary. This also reduces the risk of errors.
