List and describe the steps of the Cyber-Attack Lifecycle. Which three important security considerations are associated with virtualization? Zero day. Malware that locks a computer or device (locker ___) or encrypts data (crypto ___) on an infected endpoint with an encryption key that only the attacker knows, thereby making the data unusable until the victim pays a ransom (usually cryptocurrency, such as Bitcoin). A Zero Trust network security model is based on which security principle? The Data Link layer of the OSI model is further divided into these two sublayers: ___ and ___, Logical Link Control (LLC) and Media Access Control (MAC), Which four layers comprise the TCP/IP model? Transition from outside to inside data center. Following a successful exploit, the attacker can disable the target application (resulting in a denial-of-service state), or can potentially access to all the rights and permissi… What is the main disadvantage of application whitelisting related to exploit prevention? External threat answers have accounted for the majority of data breaches over the past five years. The ability to use a single signature (fingerprint) to detect never before seen computer viruses. Behavior-based detection methods: In this technique, you don’t examine the code of incoming files but instead observe how it interacts with existing software. ___ is ___ that displays annoying ads on an infected endpoint often as popup banners. Surveillance software or spyware that is able to record every keystroke to a log file, usually encrypted. Locky, TeslaCrypt/EccKrypt, Cryptolocker and Cryptowall are examples of Crypto ___. A __ __ contains machine code that is loaded into an endpoint's memory by firmware during the startup process, before the OS is loaded. 3. Security personnel perform a pen test (or penetration test) to determine if attackers can exploit existing vulnerabilities, but attackers may not try to do so. able to detect zero-days’ (a mean of 17% detection). Malware that fools you into thinking it's an antivirus program rather than a virus. What are lessons or common themes that can be derived from the Target, Home Depot, Anthem, OPM, Yahoo! Which 3 options are dynamic routing protocols? As such, installing latest Exchange updates soon after Microsoft published … If the bots can't get tot their servers, they can't get new instructions, upload stolen data or do anything that makes botnets so unique and dangerous. Anomaly detection (Analysis Approach) -collecting data related to behavior of legit users over a period of time. False. ___ abuses Telegram's Bot API for C&C and data exfiltration. False. A binary or string of bits fingerprint which can be used to detect and identify specific computer viruses. It can be implemented using a simple substitution cipher such as an exclusive or (XOR) operation, in which the output is true only when the inputs are different (for example TRUE and TRUE equals FALSE but TRUE and FALSE equals TRUE) or more sophisticated encryption algorithms such as the Advanced Encryption Standard (AES). Describe the different motivations of various adversaries including cybercriminals, cyberterrorists, state-sponsored organizations and hacktivists. a. they are usually zero-day attacks and won't be detected b. they are spyware exploits that antivirus software is not able to detect c. they define files and locations that the antivirus software will not scan detect zero -day exploits . If left unaddressed, vulnerabilities create security holes that cybercriminals can exploit. It will notify you that you have a virus and tell you to purchase this software package in order to get rid of it. Viruses. Choose 3. How to Defend Against Zero-Day Attacks. Attacks that use readily available tools with little or no customization. A digital/virtual currency that uses cryptography for security. Once a session is established, individual packets that are part of the session are not inspected. At that point, it's exploited before a fix becomes available from its creator. Activities falling outside of the normal scope of operations could be an indicat… Unlike other types of malware, ___ are typically not self-replicating. Software designed to damage a computer system. (Choose four. A zero day exploit is a cyber attack that occurs on the same day a weakness is discovered in software. It can spread within your system or to other computers without any action from the user. What are three characteristics of application firewalls? A company who provides server, network and specialized applications to end users and organizations. Cloud computing doesn't mitigate existing network security risks; security requires isolation and segmentation, whereas the cloud relies on shared resources; security deployments are process-oriented, whereas cloud computing environments are dynamic. Zero-day exploits are vulnerabilities that have yet to be publicly disclosed. Signature-based anti-malware software is considered a proactive security countermeasure. ___ is estimated to have infected more than 2.4 million computers worldwide. That being said, it is possible for a behavioral IDS to identify novel attacks like zero day exploits… As with other Android malware, some apps may also be available on forums or file-sharing sites, or even may be sent to victims as email attachments. This is why the best way to detect a zero-day attack is user behavior analytics. Although the malware payload changes with each iteration - for example, by using a different code structure or sequence or by inserting garbage code to change the file size the fundamental behavior of the malware payload remains unchanged. T/F? Compatibility considerations. Furthermore, an IDS only detects ongoing attacks, not incoming assaults. A __ __ __ targets the boot sector or master boot record (MBR) of an endpoint's storage drive or other removable storage media. More focused on physical access. T/F? ___ has been primarily used to mine the Monero cryptocurrency. One end of a communication channel. This may include locking the monitor's screen or by locking user's files. Misuse/Signature detection (Analysis approach) -Uses set of known malicious data patterns or attack rules compared with current behavior. _____ is a set of IT service management best practices. What is the primary issue with a perimeter-based network security strategy today? By using similar traits as legitimate apps for example copycat iconography and app or package names, ___ lures victims into installing the malicious apps, especially when available on so-called third-party (that is, non-Google Play) app stores that often have fewer security and vetting procedures for the apps they host.
