Security Terminology Flashcards
Your manager, Wayne, is concerned about malicious users who might compromise servers and remain undetected for a period of time. What type of threat is Wayne concerned about?
Advanced persistent threat (APT)
An advanced persistent threat (APT) implies a compromised network or device, whereby malicious actors, such as competitors or hacking groups, retain control of the compromised system for a period time before being detected.
Which type of malicious users or groups attempt to promote a political or ideological view?
Hacktivist
Your organization has begun quarterly lunch-and-learn sessions to educate employees about current scams and computer security threats to increase their awareness and help prevent security issues such as data leaks. To which of the following items does this initiative best apply?
a) Hacktivist
b) Advanced persistent threat
c) State actor
d) Insider threat
Insider threat
Insider threats result from an actor within the organization who has knowledge of internal procedures, configurations, or details that would be unknown to external users. Internal user training and awareness help protect digital assets from unintentional security breaches.
Which type of malicious entity is most likely to launder the proceeds of illegal activities through online gambling sites?
Criminal syndicates
A criminal syndicate is related to organized crime, which is likely to profit through illegal means and therefore must “clean” the proceeds through laundering.
You are part of a team that has been hired to conduct penetration tests. Which term best describes your team?
Authorized hackers
Authorized hackers are the “good guys”; they are hired to perform penetration tests to identify exploitable security weaknesses.
You are an IT technician responsible for defining and implementing IT solutions throughout the organization. You have discovered that users in a remote branch office have configured a Wi-Fi network for use only in their location without approval from headquarters. Which term best describes this scenario?
Shadow IT
The term “shadow IT” refers to non-IT staff who install or configure networked devices without central approval from the IT department; this would include adding a Wi-Fi router to a network without approval.
Which type of malicious actor is the most likely to have the most resources and funding?
State actors
You have enabled firewall rules to allow only HTTPS connections to a web server that resides in your company’s server room. The company’s web site stores sensitive customer data in a backend database stored on the same host. Which types of potential security problems do company IT technicians present in this scenario? (Choose two.)
Direct physical access and Insider threat
Technicians who can gain access to the server room have direct access to the physical server and storage arrays, and physical access bypasses firewall rules. This is considered a potential insider threat.
Your organization has deployed mission-critical applications to a public cloud service provider (CSP) platform. The CSP recently disclosed a security flaw in the underlying network switches that was exploited by malicious users. The network switches were missing a firmware update that addressed security vulnerabilities. From your organization’s perspective, what is the source of this security issue?
Supply chain
In this case, the cloud service provider (CSP) is a part of the supply chain, or service delivery platform (SDP), in the sense that the CSP supplies the IT services infrastructure used by the cloud customer.
You manage an air-gapped secure network named NET1 for a utility provider. NET1 does not connect in any way to any other network. You have scheduled the automatic scanning of the network for unauthorized network devices. Recently, new malware that is active on the Internet was discovered on NET1. What is the most likely explanation for how the malware made its way to NET1?
Removable media was infected
Since NET1 has no connections to other networks, the most likely explanation is that the malware was transmitted through infected files on removable media.
After running a vulnerability scan of your entire network because of newly reported vulnerabilities on the Internet, you notice that Linux-based honeypots on your network that are intentionally configured to appear vulnerable were not reported as vulnerable. What is the most likely cause of this behavior?
The vulnerability database is not up-to-date
Vulnerability scanning tools use a database of known vulnerabilities as a comparison mechanism when scanning hosts and apps. Scanning tools can be configured to subscribe to vulnerability and threat feeds for automatic updating. If this database is not kept up-to-date, newer vulnerabilities may not be detected during scanning.
You are reviewing network analysis reports for signs that could suggest malicious activity. What are you looking for?
Indicator of compromise
Indicators of compromise (IoCs) suggest that malicious activity may be taking place or has taken place.
You are researching potential vulnerabilities with the way that Session Initiation Protocol (SIP) Voice over IP (VoIP) calls are established over the network. Which documentation source explains the standardized inner workings of SIP VoIP calls?
Request for comment (RFCs)
Requests for comment (RFCs) are publicly available technical standardization documents stemming from various international technical bodies that detail how specific types of technologies such as HTTP, DNS, or the ASCII character set work. Vendors building software and hardware products generally adhere to RFCs.
What is the primary purpose of the Tor web browser?
Accessing web anonymously
Which role is responsible for managing data in alignment with policies set forth by data owners?
Data custodian
The data custodian, or data steward, role involves managing data assets in accordance with policies set forth by data owners. An example of a data custodian is a file server administrator that can set file system permissions
