Hash Functions(cryptographic) hash functions are used to generate a one way "check sum" for a larger text, which is not trivially reversed. War DialerA computer program that automatically dials a series of telephone numbers to find lines connected to computer systems, and catalogs those numbers so that a cracker can try to break into the systems. It has no concept of a "root" superuser, and does not share the well-known shortcomings of the traditional Linux security mechanisms, such as a dependence on setuid/setgid binaries. (n.d.). Learn more about how SANS empowers and educates current and future cybersecurity practitioners with knowledge and skills. Because many intrusions occur over networks at some point, and because networks are increasingly becoming the targets of attack, these techniques are an excellent method of detecting many attacks which may be missed by host-based intrusion detection mechanisms. Retrieved October 9, 2020. T1, T3A digital circuit using TDM (Time-Division Multiplexing). SHA1A one way cryptographic hash function. accessible to those who need to use it.

Fully-Qualified Domain NameA Fully-Qualified Domain Name is a server name with a hostname followed by the full domain name. LegionSoftware to detect unprotected shares. Its architecture strives to separate enforcement of security decisions from the security policy, and streamlines the amount of software involved with security policy enforcement. Network MappingTo compile an electronic inventory of the systems and the services on your network. An Internet Document can be submitted to the IETF by anyone, but the IETF decides if the document becomes an RFC. ExposureA threat action whereby sensitive data is directly released to an unauthorized entity. System and network discovery techniques normally occur throughout an operation as an adversary learns the environment, and also to an extent in normal network operations. Threat ModelA threat model is used to describe a given threat and the harm it could to do a system if it has a vulnerability. MITRE ATT&CK and ATT&CK are registered trademarks of The MITRE Corporation. Central management of AppArmor is usually complicated considerably since administrators must decide between configuration deployment tools being run as root (to allow policy updates) or configured manually on each server. getsebool,[28] include version information, system information, or a warning about authorized use. Indirect Command Execution, Technique T1202 - MITRE ATT&CK Trojan HorseA computer program that appears to have a useful function, but also has a hidden and potentially malicious function that evades security mechanisms, sometimes by exploiting legitimate authorizations of a system entity that invokes the program. The TCP packet (and its header) are carried in the IP packet. MITRE ATT&CK and ATT&CK are registered trademarks of The MITRE Corporation. Typical policy rules consist of explicit permissions, for example, which domains the user must possess to perform certain actions with the given target (read, execute, or, in case of network port, bind or connect), and so on. Or a computer with a web server that serves the pages for one or more Web sites. BroadcastTo simultaneously send the same message to multiple recipients. Adversaries may abuse a valid Kerberos ticket-granting ticket (TGT) or sniff network traffic to obtain a ticket-granting service (TGS) ticket that may be vulnerable to Brute Force. SynchronizationSynchronization is the signal made up of a distinctive pattern of bits that network hardware looks for to signal that start of a frame. Retrieved October 28, 2020. Password CrackingPassword cracking is the process of attempting to guess passwords, given the password file information. TopologyThe geometric arrangement of a computer system. SOCKSA protocol that a proxy server can use to accept requests from client users in a company's network so that it can forward them across the Internet. Valid Accounts: Default Accounts, Sub-technique T1078.001 Attacking Kerberos - Kicking the Guard Dog of Hades. Mac Threat Response, Mobile Research Team. OSI layersThe main idea in OSI is that the process of communication between two end points in a telecommunication network can be divided into layers, with each layer adding its own set of special, related functions. Computer NetworkA collection of host computers together with the sub-network or inter-network through which they can exchange data. The process on the router that is running the routing protocol, communicating with its neighbor routers, is usually called a routing daemon. Issue-Specific PolicyAn Issue-Specific Policy is intended to address specific needs within an organization, such as a password policy. Digital CertificateA digital certificate is an electronic "credit card" that establishes your credentials when doing business or other transactions on the Web. Business Continuity Plan (BCP)A Business TLS is the successor to the Secure Sockets Layer. Receive curated news, vulnerabilities, & security awareness tips, South Georgia and the South Sandwich Islands. CollisionA collision occurs when multiple systems transmit simultaneously on the same wire. Private AddressingIANA has set aside three address ranges for use by private or non-Internet connected networks. MultiplexingTo combine multiple signals from possibly disparate sources, in order to transmit them over a single path. Frequently used hash functions are MD5 and SHA1. EncapsulationThe inclusion of one data structure within another structure so that the first data structure is hidden for the time being. Kerberoasting Split HorizonSplit horizon is a algorithm for avoiding problems caused by including routes in updates sent to the gateway from which they were learned. SELinux is popular in systems based on linux containers, such as CoreOS Container Linux and rkt. The routers must communicate using a routing protocol, of which there are many to choose from. Adversaries may use scripts automatically executed at boot or logon initialization to establish persistence. Poison ReverseSplit horizon with poisoned reverse (more simply, poison reverse) does include such routes in updates, but sets their metrics to infinity. SocketThe socket tells a host's IP stack where to plug in a data stream so that it connects to the right application. Business Impact Analysis (BIA)A Business Impact Analysis determines what levels of impact to a system are tolerable. The output is formatted to be compatible with cracking tools like John the Ripper and Hashcat. Intended to specify an unclassified, It is defined in RFC 1203 (v3) and RFC 2060 (v4). A honey pot can be used to log access attempts to those ports including the attacker's keystrokes. Hybrid AttackA Hybrid Attack builds on the dictionary attack method by adding numerals and symbols to dictionary words. HopsA hop is each exchange with a gateway a packet takes on its way to the destination. ID Name Description; G0119 : Indrik Spider : Indrik Spider used wmic.exe to add a new user to the system. SteganographyMethods of hiding the existence of a message or other data. They can make filtering decisions based on IP addresses (source or destination), Ports (source or destination), protocols, and whether a session is established. Log ClippingLog clipping is the selective removal of log entries from a system log to hide a compromise. This can be achieved by corrupting a DNS server on the Internet and pointing a URL to the masquerading websites IP. A datagram or packet needs to be self-contained without reliance on earlier exchanges because there is no connection of fixed duration between the two communicating points as there is, for example, in most voice telephone conversations. SmurfThe Smurf attack works by spoofing the target address and sending a ping to the broadcast address for a remote network, which results in a large amount of ping replies being sent to the target. Layer 2 Tunneling Protocol (L2TP)An extension of the Point-to-Point Tunneling Protocol used by an Internet service provider to enable the operation of a virtual private network over the Internet. AuthenticationAuthentication is the process of confirming the correctness of the claimed identity. Digest AuthenticationDigest Authentication allows a web client to compute MD5 hashes of the password to prove it has the password. DMZ's provide either a transit mechanism from a secure source to an insecure destination or from an insecure source to a more secure destination. Information repositories are tools that allow for storage of information, typically to facilitate collaboration or information sharing between users, and can store a wide variety of data that may aid adversaries in further objectives, or direct access to the target information. PossessionPossession is the holding, control, and ability to use information. IMAP is intended as a replacement for or extension to the Post Office Protocol (POP). (2011, February). In the case of file systems, mapping between files and the security contexts is called labeling. The specific physical, i.e., real, or logical, i.e., virtual, arrangement of the elements of a network. [6], Dtracks RAT makes a persistent target file with auto execution on the host start. critical resources and facilitate the continuity of operations in an Turla uses HyperStack, Carbon, and Kazuar to compromise government entity. TCP WrapperA software package which can be used to restrict access to certain network services based on the source of the connection; a simple tool to monitor and control incoming network traffic. Refers to the transmission of data in two directions simultaneously. ConfidentialityConfidentiality is the need to ensure that information is disclosed only to those who are authorized to view it. [1][2][3], Default accounts are not limited to client machines, rather also include accounts that are preset for equipment such as network devices and computer applications whether they are internal, open source, or commercial. Kernel Experimental ports of the FLASK/TE implementation have been made available via the TrustedBSD Project for the FreeBSD and Darwin operating systems. Kerberoasting Without Mimikatz. instructions for a problem-solving or computation procedure, especially List Based Access ControlList Based Access Control associates a list of users and their privileges with each object. ARPANETAdvanced Research Projects Agency Boot or Logon Initialization Scripts For example, using a (more expensive) phone call vs. sending an e-mail in order to avoid risks associated with e-mail may be considered "Risk Averse". A Unix program that takes an e-mail address as input and returns information about the user who owns that e-mail address. [13][7], SILENTTRINITY contains a module to conduct Kerberoasting. It (2018, December 9). IP FloodA denial of service attack that sends a host more echo request ("ping") packets than the protocol implementation can handle. FramesData that is transmitted between network points as a unit complete with addressing and necessary protocol control information. (2020, October 28). AppletJava programs; an application program that uses the client's web browser to provide a user interface. Exponential Backoff AlgorithmAn exponential backoff algorithm is used to adjust TCP timeout values on the fly so that network devices don't continue to timeout sending data over saturated links. Whereas SELinux re-invents certain concepts to provide access to a more expressive set of policy choices, AppArmor was designed to be simple by extending the same administrative semantics used for DAC up to the mandatory access control level. Examples would be the Linefeed, which is ASCII character code 10 decimal, the Carriage Return, which is 13 decimal, or the bell sound, which is decimal 7.
