NIST Drafts Cybersecurity Guidance

The National Institute for Standards and Technology is urging the government to continuously monitor its own cybersecurity efforts.

Finally, and perhaps most significantly, the document advises federal agencies to put continuous monitoring in place. Software, firmware, hardware, operations, and threats change constantly. Within that flux, security needs to be managed in a structured way, Ross says.

"We need to recognize that we work in a very dynamic operational environment," Ross says. "That allows us to have an ongoing and continuing acceptance and understanding of risk, and that ongoing determination may change our thinking on whether current controls are sufficient."

The continuous risk management step might include use of automated configuration scanning tools, vulnerability scanning, and intrusion detection systems, as well as putting in place processes to monitor and update security guidance and assessments of system security requirements.

NIST will keep public comment on Special Publication 800-37 open until the end of the year.

The new document is the second in a series of five that aims to create a more consistent, unified framework for federal cybersecurity. A consortium of agencies, which includes representatives from the military, intelligence agencies, and civilian agencies, is behind the creation of the series.

The first in the series, Special Publication 800-53, provided updated recommendations on security controls. The other three documents will advise federal agencies on how to assess the effectiveness of security measures, provide an enterprise architecture lens through which to look at cybersecurity, and how to assess risk and tackle existing problems.

Over the coming year or two, NIST also plans to help integrate cybersecurity guidance into the government's official Federal Enterprise Architecture methodology, release a technical cybersecurity framework for systems and security engineering, and take on a more public face to encourage culture change in terms of cybersecurity.

Enterprise Vulnerabilities
From DHS/US-CERT's National Vulnerability Database
CVE-2014-2208
Published: 2014-12-28
CRLF injection vulnerability in the LightProcess protocol implementation in hphp/util/light-process.cpp in Facebook HipHop Virtual Machine (HHVM) before 2.4.2 allows remote attackers to execute arbitrary commands by entering a \n (newline) character before the end of a string.

CVE-2014-2209
Published: 2014-12-28
Facebook HipHop Virtual Machine (HHVM) before 3.1.0 does not drop supplemental group memberships within hphp/util/capability.cpp and hphp/util/light-process.cpp, which allows remote attackers to bypass intended access restrictions by leveraging group permissions for a file or directory.

CVE-2014-5386
Published: 2014-12-28
The mcrypt_create_iv function in hphp/runtime/ext/mcrypt/ext_mcrypt.cpp in Facebook HipHop Virtual Machine (HHVM) before 3.3.0 does not seed the random number generator, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging the use of a single initial...

CVE-2014-6228
Published: 2014-12-28
Integer overflow in the string_chunk_split function in hphp/runtime/base/zend-string.cpp in Facebook HipHop Virtual Machine (HHVM) before 3.3.0 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted arguments to the chunk_split ...

CVE-2014-6229
Published: 2014-12-28
The HashContext class in hphp/runtime/ext/ext_hash.cpp in Facebook HipHop Virtual Machine (HHVM) before 3.3.0 incorrectly expects that a certain key string uses '\0' for termination, which allows remote attackers to obtain sensitive information by leveraging read access beyond the end of the string,...
