--The Best Cybersecurity Book of 2019: Sandworm: A New Era of CyberWar

(Nov. 22, 2019)

Sandworm answers the questions security people need answered about how the most damaging cyber attacks of the past three years happened, who was at fault, and perhaps most importantly, what did the victims not do that would have protected them. What makes it this year's "best book" is the way it takes the reader inside discussions with the people who actually discovered and deciphered the attacks as well as discussions with the victims. Written by one of America's "10 Top Cyber Journalists," Andy Greenberg, Sandworm is an in-person tour of the battlefield with face to face discussions with each of the people you would want to talk to. Just amazing!

--DHS and VotingWorks Release Open Source Post Election Audit Tool

(November 21, 2019)

The US Department of Homeland Security's (DHS's) Cybersecurity and Infrastructure Security Agency (CISA) and VotingWorks have made an open source post election risk-limiting audit tool available on GitHub. Arlo, as the tool is named, "helps election officials complete a statistically valid audit of vote tabulation processes by comparing the votes marked on a random sample of original paper ballots with the electronically recorded votes for those same ballots."

--Critical Flaws in Oracle E-Business Suite

(November 19 & 20, 2019)

A pair of critical vulnerabilities in Oracle's E-Business Suite (EBS) could be exploited to print checks and conduct electronic funds transfers. Oracle released fixes for the flaws in its April 2019 Critical Patch Update. The Onapsis researchers that found the flaws and reported them to Oracle in December 2018 estimate that about half of Oracle EBS customers have not yet applied the fixes.


[Editor Comments]


[Neely] Regression testing of changes to ERP systems is important, and it takes a lot of maturity to roll updates quickly. Due to the critical nature of the flaws, expedited testing is warranted; mitigate some of the risks by actively watching application logs for unauthorized transactions.

--New Russian Law Requires Devices Sold Have Russian Software Pre-Installed

(November 21, 2019)

Russia's parliament has passed a law that would prohibit the sale of certain electronic devices that do not have Russian software pre-installed. The law affects smartphones, computers, and smart TVs. Devices made in other countries may be sold with their own software, but the Russian software must be installed as well. While the law has been touted as promoting Russian software and making devices easier to use in that country, some are concerned that the law will increase surveillance.


[Editor Comments]


[Pescatore] This is a complex issue. Back in 1999, China started trying to mandate use of Chinese encryption software and standards in everything and largely backed off. It has now focused on a "Multi Level Procurement Standard" that only imposes domestic Intellectual Property requirements on use cases with higher levels of impact, similar to what the US calls Critical Infrastructure Systems. The US more recently has simply issued bans on software and hardware from Chinese and Russian suppliers for government use, regardless of criticality, while the UK has taken more of a required testing approach. There are no examples of positive outcomes when governments require software from their own countries get installed on commercial products.


[Neely] As John says, this is complicated and will change over time. Expect trade restrictions and interplay with their ISP restrictions to come into play to force the issue.

--Cleveland Federal Reserve President: Do a Better Job of Sharing Threat Information

(November 21, 2019)

Cleveland Federal Reserve President Loretta Mester said that financial organizations need to undergo tests to see how they handle cyberattacks, noting that "Such a test could help evaluate the financial system's plans for data and core systems recovery and its reliance on third parties to implement that plan." Mester also said that financial organizations, regulators, and government agencies need to do a better job of collaborating and sharing threat information. Mester spoke at a conference on financial stability hosted by the Cleveland Federal Reserve.
