Network Security Risk

Question 1

What are the network risks associated with People?

Answer 1

• Intruders or attackers using social engineering or snooping to obtain user passwords
• An administrator incorrectly creating or configuring user role and permission resulting in file and login access vulnerabilities
• Network administrators overlooking security mistakes in topology or hardware configuration
• Lack of proper documentation and communication of security policies, leading to intentional or un-intentional misuse of files or network access
• An unused computer or terminal being left logged onto the network, thereby providing an entry point for an intruder
• Users or administrators choosing easy-to-guess passwords
• Authorized staff leaving computer room doors open or unlocked, allowing unauthorized individuals to enter
• Staff throwing a way backup disk or storage in public dustbins
• Admins neglecting to remove acounts who have left the organization
• Users writing their passwords on paper, then placing the paper in an easily accessible place.

• Jon Jones snooping arround trying to user social engineering to steal ankaleav’s password as ankaleve is the ufc account admin
• Ankalaev is create other ufc fighters accounts and accidenly grants DDP an admin role and permissions
• DPP see ankalaev mistake and just overlooks the flaw
• JDM is mad that these errors happen and he gatthers every one to document and communicate the security policies
• Islam is in meeting with his computer but leaves it open
• volkanovski sees islam’s laptop open and gues his account passwor as password and it unlocks
• Pathoja leaves comes and see volkanovski the room and tells him to leave but then pantoja forgets to lock the door
• Francis is hungry and searches the dustbins while there he finds a hard drive
• Adesanya ask him for the hard drive as he knows he can access it becauser the ufc did not delete his account when they fired him
• Usman comes out the bin and tells adensanya there is not need he already found a password on the paper

Question 2

What are the securiy risk associated with hardware and Network Desing?

Answer 2

• Wireless and wire-based transmissions can often be intercepted.
• Networks that use leased public lines, the Internet, are vulnerable to eavesdropping.
• Network hubs broadcast traffic over the entire segment, thus making transmissions more widely vulnerable to sniffing.
• Unused routers, ports can be exploited and accessed by crackers if they are not disabled.
• If routers are not properly configured to mask internal subnets, users on outside networks (such as the Internet) can read the private addresses.
• Modems attached to network devices may be configured to accept incoming calls, thus opening security holes if they are not properly protected.
• Dial-in access servers used remote staff may not be carefully secured and monitored.
• Computers hosting very sensitive data may coexist on the same subnet with computers open to the general public.

• The alpaka conects his pc to a router using an ethernet cable
• The beaver tells him thier network uses a public line so it vulnerable to eves dropping
• The crocodile proposes the use a hub instead of a router
• The dragon connects last after everyone on the hub but, One port is still empty
• the Elephant looks at his screen all the is maxed out subnet mask on his screen
• The Fox takes a call on his whatsapp while all of this is going on
• The Girrafe is not at the home and Dails in (vid call to see every one)
• In the back of all of this the Hippo is strungulling to fix the house server

Question 3

What are the risks associted with protocols and software?

Answer 3

• TCP/IP contains several security flaws. For example, IP addresses can be falsified easily or TCP requires only weak authentication.
• Trust relationships between one server and another may allow a cracker to access the entire network because of a single flaw.
• Network operating system software typically contains “backdoors” or security flaws. Unless the network administrator performs regular updates, a cracker may exploit these flaws.
• If someonce access the comant prompt the could run hamful commands to damage the operating system.
• Administrators might accept the default security options after installing an operating system or application.

• Curry complaning that there is too many defensive flaws in the team
• KD says the only way to improve defence is throught trust
• Klay says the best way is to update the defence strategy
• Dramon green selling the defence tacktics in the back to ant
• Ant accepting the defence tacktics like is the gospel truth

Question 4

What are the network security risk associated with Internet access

Answer 4

• Firewalls: A poorly configured firewall may fail to block unauthorized data packets from the internet.
• Hackers: Hackers can gather user ID information from online forms, mailing lists, or newsgroups.
• Flashing: During online chat sessions, attackers can send commands that disrupt the user’s screen (flashing attacks).
• DOS: Denial-of-service (DoS) attacks can overload a system with too much traffic, making it unusable.
• Updates: Failing to do updates regularly makes systems more vulnerable to attacks.
