signature detection is designed to detect zero day exploits quizlet
A __ __ is a cryptographic representation of an entire file or program's source code. ___ is ___ that displays annoying ads on an infected endpoint often as popup banners. False. They are only dangerous if given a chance to run. Actually, a zero-day exploit, also known as a zero-hour exploit, is a software vulnerability no one but the cybercriminal who created it knows about and for which there is no available fix. T/F? Is a security system that consists of security software on a centrally managed and accessible server or gateway within a network, in addition to client software being installed on each of the endpoints or devices. A type of malware that prevents or limits users from accessing their system. (Choose two). ___ has been primarily used to mine the Monero cryptocurrency. (Choose one.). They can only detect known threats and hence, are not efficient in detecting unknown threats. A Chinese-affiliated advanced persistent threat group known as APT31 used attack tools belonging to an NSA-sponsored APT for years, according to new Check Point research. Endpoints are where hacker activity takes place. Provide real-time on-agent prevention and detection, without the need for constant remote connectivity or updates. The attacker attempts to infect as many endpoints as possible and the endpoints can then be used to send out spam email messages without the end users' knowledge. ___ could send up to 25,000 spam email messages per hour from an individual bot and at its peak sent an average of 192 spam emails per minute per bot. Which three important security considerations are associated with virtualization? Internet advertising used to spread malware. 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. Compatibility considerations. It comes equipped with several features including providing mining stats to users, configuring various processor loads for the running miner the ability to infect USB devices and the ability to load additional DLLs on the victim. A remote administration tool maliciously installed as a Trojan horse to give a remote user some level of control of the infected system. The Cyber-Attack Lifecycle is a seven-step process. Describe the different motivations of various adversaries including cybercriminals, cyberterrorists, state-sponsored organizations and hacktivists. An organization can be fully compliant with the various cybersecurity laws and regulations that are applicable for that organization, yet still not be secure. A company who provides server, network and specialized applications to end users and organizations. 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. The paper then investigates how the zero-days’ are detected, how prone the corresponding signatures are to false alarms, and how easily they can be evaded. 3. T/F? The Cyber-Attack Lifecycle is a five-step process that an attacker goes through to attack a network. and Equifax cyber attack examples? Software designed to damage a computer system. ___ botnets such as ZeuS and SpyEye are responsible for the direct theft of funds from all types of enterprises. A _____ allows multiple, virtual operating systems to run concurrently on a single physical host computer. Algorithms can quickly and efficiently scan an object to determine its digital signature.When an anti-malware solution provider identifies an object as malicious, its signature is added to a database of known malware. You can create a secure network that is resilient against zero-day attacks. Malware that allows an attacker to bypass authentication to gain access to a compromised system. 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). How you can detect zero day exploit. A __ __ __ targets the boot sector or master boot record (MBR) of an endpoint's storage drive or other removable storage media. A digital/virtual currency that uses cryptography for security. While this method has limited effectiveness and is subject to false positives/negatives, it can work well in a hybrid solution. Telegram Bots are special accounts that do not require an additional phone number to set up and are generally used to enrich Telegram chats with content from external services or to get customized notifications and news. Reveton and LockeR are 2 examples of locker ___. Zero-day exploits tend to be very difficult to detect. A sophisticated, possibly long-running computer hack that is perpetrated by large, well-funded organizations such as governments, Attack floods a network or server with service requests to prevent legitimate users' access to the system, Performs threat inspection and takes action prescribed in Security Profiles. T/F? Wired Equivalent Privacy (WEP) is an effective protocol for securing wireless networks. ___ botnet attacks are a type of cyberattack in which extremely high volumes of network traffic such as packets, data or transactions are sent to the target victim's network to make their network and systems (ie e-commerce website or web app) unavailable or unusable. Malware that typically targets a computer network by replicating itself to spread rapidly. Alternatively, a packer can be used to compress a malware program for delivery then decompress it in memory at run time. Network firewalls cannot completely protect hosts from zero-day exploits. 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). Malware that fools you into thinking it's an antivirus program rather than a virus. Policy-based approach to network security that requires endpoint devices to comply with specific rules before network resource access is given. Signature-based security solutions can’t detect a zero-day exploit, and there are no software vulnerability patches immediately available. T/F? A place where communications start and end. In March 2011 the FBI workign with Microsoft and others were able to take down the ___ botnet which had operated for more than 5 years and at the time was responsible for sending up to 60% of the world's spam. Network firewalls cannot completely protect hosts from zero-day exploits. According to Verizon's 2018 Data Breach Investigations Report, internal threat actors are responsible for about 28 percent of reported data breaches. Process of writing or reading secret codes. The ___ is a distributed, hierarchical internet database that maps FQDNs to IP addresses. Zero-day exploits are vulnerabilities that have yet to be publicly disclosed.
