National Science and Technology Council Report: Preparing for the Future of Artificial Intelligence

whitehouse-artificialintelligencepreparations

AI has applications in many products, such as cars and aircraft, which are subject to regulation designed to protect the public from harm and ensure fairness in economic competition. How will the incorporation of AI into these products affect the relevant regulatory approaches? In general, the approach to regulation of AI-enabled products to protect public safety should be informed by assessment of the aspects of risk that the addition of AI may reduce alongside the aspects of risk that it may increase. If a risk falls within the bounds of an existing regulatory regime, moreover, the policy discussion should start by considering whether the existing regulations already adequately address the risk, or whether they need to be adapted to the addition of AI. Also, where regulatory responses to the addition of AI threaten to increase the cost of compliance, or slow the development or adoption of beneficial innovations, policymakers should consider how those responses could be adjusted to lower costs and barriers to innovation without adversely impacting safety or market fairness.

(U//FOUO) DHS Assessment: Cyber Threats and Vulnerabilities to US Election Infrastructure

dhs-electioncyberthreats

DHS has no indication that adversaries or criminals are planning cyber operations against US election infrastructure that would change the outcome of the coming US election. Multiple checks and redundancies in US election infrastructure—including diversity of systems, non-Internet connected voting machines, pre-election testing, and processes for media, campaign, and election officials to check, audit, and validate results—make it likely that cyber manipulation of US election systems intended to change the outcome of a national election would be detected.

DHS US-CERT Understanding Distributed-Denial-of-Service Attacks

dhs-understandingddos

One of the most significant cyber threats to businesses, local and federal government agencies is the Distributed-Denial-of-Service attack (DDoS). A Distributed Denial of Service attack (DDoS) occurs when an attacker commands a number of computers to send numerous requests to a target computer. The overwhelming flood of requests to the website or computer network can cause it to shut down or fail to handle the requests of legitimate users, much like a rush hour traffic jam on the freeway. This type of attack can completely disrupt an organization’s operations until the network is able to be restored. Understanding the basic concept and methods of a DDoS attack can help operators of both large and small networks mitigate the severity of the attack.

DoD Online Privacy and Operational Security Smart Cards: Facebook Mobile

DoD-FacebookMobilePrivacy

As of January 2015, Facebook Mobile hosts 745 million daily mobile active users who accounts for over 60% of all mobile posts published to any online social networking service. Though privacy can still be achieved, mobile users place their personal identity data at a greater risk when compared to users logging in via desktop computer. This is in large part due to the fact that mobile devices provide Facebook with a means to access additional location information, contact lists, photos, and other forms of personal data. Use the following recommendations to best protect yourself against oversharing.

FBI Cyber Bulletin: Identification of Locky Ransomware

FBI-LockyRansomware

The ‘Locky’ malware is a ransomware variant, which has extensively utilized spam campaigns to distribute malicious files that download and execute code capable of encrypting numerous critical file types on both local and networked file stores. Encrypted files are renamed with a unique hexadecimal filename and receive the “.locky” extension. Each directory containing encrypted files contains instructions on how to utilize Bitcoin in order to pay a ransom for file recovery, and the system’s computer background is also changed to contain payment instructions. Recovery of encrypted files is impossible without data backup or acquisition of the private key due to the well-implemented, strong encryption. Historically, while payment of the ransom may result in receipt of the valid private key, enabling decryption of the targeted files, the FBI does not recommended the victim pay the ransom.
