HIDS/HIPS - ANSWER - Host-Based,
- monitors the characteristics of a single host and the events occurring within that host for suspicious
activity and most commonly deployed on critical hosts such as publicly accessible servers and servers
containing sensitive information
- network traffic (only for that host), system logs, running processes, application activity, file access and
modification, and system and application configuration changes.
NIST SP 800-60, Rev 1 - ANSWER Security Categorization
NIST SP 800-122 - ANSWER Categorizing PII
FIPS-199 - ANSWER Security Categorization
FIPS-200 - ANSWER Minimum Security Requirements
NIST SP 800-18, Rev 1 - ANSWER System Security Plan
NIST SP 800-30, Rev 1 - ANSWER Risk Assessment
Please note that original version has been replaced by 800-39, which is Risk Management
,Risk Impact - ANSWER Risk associated with the operation and use of information systems that support
the missions and business functions of their organizations
NIST SP 800-34 - ANSWER Contingency Planning for IT Systems
NIST SP 800-37, Rev 2 - ANSWER RMF/Roles and Process
FIPS 180-2 - ANSWER - Secure Hash Standard
- Federal agencies must use the Secure Hash Standard if we use hashing
- Provides Integrity
- SHA (Secure Hash Algorithm) there are 4 hash algorithms (SHA-1, SHA-256, SHA-384, SHA-512)
- Secure because a change to a message results in a different message digest.
- Other non-standard hash algorithms (MD2, MD5, CRC, HAVAL)
FIPS 186-2 - ANSWER - Digital Signature Standard
- Provides integrity (message digest) and nonrepudiation (only I have my private key)
- Algorithms
- Digital Signature Algorithm (DSA)
- RSA digital signature algorithm, specified in American National Standard (ANS) X9.31 and Public - Key
Cryptography Standard (PKCS)
- Elliptic Curve Digital Signature Algorithm (ECDSA), specified in ANS X9.62. FIPS 186-3 approves the use
of ECDSA
FIPS 197 - ANSWER - specifies AES, Advanced Encryption Standard
- uses Rijndael Algorithm
- Encrypting is best way to provide confidentiality
- Symmetric encryption - faster than asymmetric encryption
- Cipher Key lengths -128, 192, 256 - three "flavors"
FIPS 198-1 - ANSWER - Keyed Hash Message Authentication Code (HMAC)
, - Purpose of a MAC is to authenticate both the source of the message and its integrity.
- HMACs have 2 parameters: 1) Message input and 2) secret key known only to originator and intended
receiver.
- HMAC is used by the message sender to produce a value (the MAC) that is formed by hashing the
secret key and the message input.
FIPS 140-2 - ANSWER - Security Requirements for Cryptographic Modules
- Level 1: Basic Security.
Atleast one approved algorithm or approved security function shall be used
- Level 2: Adds tamper evident coatings, adds role-based authentication
Tamper evidence
Role based, e.g. AD security groups, user account inherit rights of the group
- Level 3: Adds identity based authentication,
intrusion prevention, and
critical access parameters
- Level 4: requires any tampering of the module to erase all critical security information/self-destruction
e.g., Bitlocker
Environmental protection
- FIPS 140-2 establishes with Cryptographic Module Validation Program
FIPS 201-2 - ANSWER - PIV
- HSPD 12
M-14-03 - ANSWER - Continuous monitoring (REMOVED 3 year authorization requirement if CM is in
place)
M-11-11 - ANSWER - PIV
CNSSI-1253, Version 1 - ANSWER NSS C&A process
, Which law requires annual IT Reporting to Congress? - ANSWER Clinger Cohen Act
what is the Best method for integrity? - ANSWER - Best method for integrity is hashing; if there is a
different message digest we know the content has changed
What is another name for the Clinger Cohen Act? - ANSWER Information Technology Management
Reform Act of 1996
Which law/regulation requires agencies annual Reporting to OMB? - ANSWER - FISMA
- Also requires Annual Reviews, Must cover:
1) Adequacy/effectiveness of Security Program,
2) Adequacy of plans or reports for budget,
3) Significant deficiency
What do digital signatures provide? - ANSWER - Provides integrity (message digest) and nonrepudiation
(only I have my private key)
- Algorithms
- Digital Signature Algorithm (DSA)
- RSA digital signature algorithm, specified in American National Standard (ANS) X9.31 and Public - Key
Cryptography Standard (PKCS)
- Elliptic Curve Digital Signature Algorithm (ECDSA), specified in ANS X9.62. FIPS 186-3 approves the use
of ECDSA
Which requires Accreditation at minimum every 3 years? - ANSWER OMB Circular A-130
what is the best method for confidentiality? - ANSWER - Best method for confidentiality is ENCRYPTION
Which requires agencies to develop a system security Plan? - ANSWER - FISMA
- OMB Circular A-130
