Hackers – This group of criminals breaks into computers or networks to gain access for various reasons. White hat attackers break into networks or computer systems to discover weaknesses in order to improve the security of these systems. Gray hat attackers are somewhere between white and black hat attackers. The gray hat attackers may find a vulnerability and report it to the owners of the system if that action coincides with their agenda. Black hat attackers are unethical criminals who violate computer and network security for personal gain, or for malicious reasons, such as attacking networks. a re m w nso ack Ra att Presentation_ID © 2008 Cisco Systems, Inc.

Each have their own motives: 2. Script Kiddies - Teenagers or hobbyists mostly limited to pranks (tricks or jokes) and vandalism (ruin), have little or no skill, often using existing tools or instructions found on the Internet to launch attacks. 3. Vulnerability Brokers - Grey hat hackers who attempt to discover exploits and report them to vendors, sometimes for prizes or rewards. bug bounty https://hackerone.com/opportunities/all 4. Hacktivists - Grey hat hackers who rally and protest against different political and social ideas. Hacktivists publicly protest against organizations or governments by posting articles, videos, leaking sensitive information, and performing distributed denial of service (DDoS) attacks.

Cisco Confidential 18 Spreading Cybersecurity Threats How Threats Spread Attacks can originate from within an organization or from outside of the organization, as shown in the figure. Internal Security Threats  An internal user, such as an employee or contract partner, can accidently or intentionally  Internal threats have the potential to cause greater damage than external threats because internal users have direct access to the building and its infrastructure devices. Internal attackers typically have knowledge of the corporate network, its resources, and its confidential data. They may also have knowledge of security countermeasures, policies and higher levels of administrative privileges. External Security Threats  External threats from amateurs or skilled attackers can exploit vulnerabilities in networked devices, or can use social engineering, such as trickery, to gain access.  External attacks exploit weaknesses or vulnerabilities to gain access to internal resources. Presentation_ID © 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 19 Spreading Cybersecurity Threats How Threats Spread (Cont.) Vulnerabilities of Mobile Devices - In the past, employees typically used company-issued computers connected to a corporate LAN.  Today, mobile devices such as iPhones, smartphones, tablets, and thousands of other devices, are becoming powerful substitutes for, or additions to, the traditional PC.  More and more people are using these devices to access enterprise information. Bring Your Own Device (BYOD) is a growing trend.  The inability to centrally manage and update mobile devices poses a growing threat to organizations that allow employee mobile devices on their networks. LAN: Local Area Network Presentation_ID © 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 20 Spreading Cybersecurity Threats How Threats Spread (Cont.)  Emergence Internet-of-Things - The Internet of Things (IoT) is the collection of technologies that enable the connection of various devices to the Internet.  IoT technologies enable people to connect billions of devices to the Internet. These devices include appliances, locks, motors, and entertainment devices, to name just a few.  This technology affects the amount of data that needs protection. Users access these devices remotely, which increases the number of networks requiring protection.  With the emergence of IoT, there is much more data to be managed and secured. All of these connections, plus the expanded storage capacity and storage services offered through the Cloud and virtualization, has led to the exponential growth of data. Presentation_ID © 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 21 Spreading Cybersecurity Threats How Threats Spread (Cont.) Impact of Big Data – Big data is the result of data sets that are large and complex, making traditional data processing applications inadequate. Big data poses both challenges and opportunities based on three dimensions:  The volume or amount of data  The velocity or speed of data  The variety or range of data types and sources There are numerous examples of big corporate hacks in the news. As a result, enterprise systems require dramatic changes in security product designs and substantial upgrades to technologies and practices. Additionally, governments and industries are introducing more regulations and mandates that require better data protection and security controls to help guard big data.

Cisco Confidential 22 Spreading Cybersecurity Threats Threat Complexity Advanced Weapons  Advanced Persistent Threat (APT) is a continuous computer hack that occurs under the radar against a specific object. Criminals usually choose an APT for business or political motives.  Algorithm attacks can track system self-reporting data, like how much energy a computer is using, and use that information to select targets or trigger false alerts. Algorithmic attacks are more devious because they exploit designs used to improve energy savings, decrease system failures, and improve efficiencies.  Intelligent selection of victims. In the past, attacks would select the low hanging fruit or most vulnerable victims. Many of the most sophisticated attacks will only launch if the attacker can match the signatures of the targeted victim. Broader Scope and Cascade Effect  Federated identity management refers to multiple enterprises that let their users use the same identification credentials gaining access to the networks of all enterprises in the group. The goal of federated identity management is to share identity information automatically across castle boundaries.  The most common way to protect federated identity is to tie login ability to an authorized device.

Watch this video https://www.youtube.com/watch?v=dVW1FNWSaTg Safety Implications  There are many safety implication associated with the dark forces of cyber security including emergency call centers in the U.S. are vulnerable to cyberattacks that could shut down 911 networks, jeopardizing public safety.  A Telephone Denial of Service (TDoS) attack uses phone calls against a target telephone network tying up the system and preventing legitimate calls from getting through.  The next generation 911 call centers are vulnerable because they use Voice-over-IP (VoIP) systems rather than traditional landlines. Heightened Recognition of Cybersecurity Threats  The defenses against cyberattacks at the start of the cyber era were low. A smart high school student or script kiddie could gain access to systems.  Now, countries across the world have become more aware of the threat of cyberattacks. The threat posed by cyberattacks now head the list of greatest threats to national and economic security in most countries.
