Introduction System Protection Malware Cyber-security Finale

What is IS Security?

Information system security is the software and hardwaremechanisms that prevent access to certain system resources:

Access Control and restrictions per user per role;

System policy and restrictions; and

Access Control and restriction per network/machine per role.

What IS security does include?

Prevention of

System level security (e.g., OS attacks, application overflow,etc.);

Network level security (e.g., network data evesdroping,machine impersonization, etc.);

Physical attacks (e.g., boot computer with OS DVD);

IS attacks via modified hardware [e.g., Mifare attacks (RFIDsystems), etc.] and

IS malfunction via Hardware I/O attacks (e.g., USB deviceplugged into a system).

Root kit A collection of programs that enableadministrator-level access to a computer or computernetwork.Backdoor A method, often secret, of bypassing normalauthentication in a product, computer system, cryptosystemor algorithm etc.Fake Antivirus It masquerades as legitimate software, but isactually a malicious program that extorts money from you to“fix” your computer.Spy Trojans Usaually a standalone program that allows ahacker to monitor user’s activities on an infected computer.Typically, they capture screen, keyboard, I/O operations.Trojans to hide Trojans Malicious software that hides itself,so its activity doesn’t appear in the list of processes.OS kernel module Trojans A kind of Trojan horse whichcombines with kernel Rootkit technologies.

Network Security Malware

Port scanners (which posts are open?) and TCPFingerprinters (Detecting remote OS and its version).

Magic Packet Activated Backdoor The backdoor opens aport, executes a signle command, initiates a session orperform some other action when it received a single magicpacket.

IP Address Spoofing A hijacking technique in which acracker masquerades as a trusted host to conceal his identity(e.g., sending e-mail from…NASA!).

Synchronize Packet Flood A cracker sends many connectionrequests in a rapid pace without responding. This activityleaves the first packet in the buffer so that other legitimateconnection requests cannot be completed

Sniffer A network sniffers monitors data flowing overcomputer network links.

Network Security Malware II

Man-in-the-middle Attacks � type of cyberattack where amalicious actor inserts him/herself into a conversationbetween two parties, impersonates both parties and gainsaccess to information that the two parties were trying to sendto each other.Remote �xploits Exploits done remotely by a cracker acrossthe Internet or by a user’s having privileges on the system.Example: Fred Durst’s home computer was remotelyattacked and someone made a copy of a 2003 three-minuteprivate video in Durst’s possession.Denial of Service (DoS) An attacker attempts to preventlegitimate users from accessing information or services. Bytargeting your computer and its network connection, or thecomputers and network of the sites you are trying to use, anattacker may be able to prevent you from accessing websitesor other services that rely on the affected computer.

What is Cryptography?

Cryptography is the art and science of keeping informationsecure from unintended audiences.

It is achieved by making information unintelligible.

Here is how it works:

plaintextencryption

ciphertextdecryption

plaintext

Example: Caesar’s cipher is a type of substitution cipher inwhich each letter in the plaintext is “shifted” a certainnumber of places down the alphabet. For instance the word“Lillija” is ecrypted as “Uruursj” if we shift 9 places.

Post-quantum cryptography.
