The document discusses various topics related to computer security including definitions of computer security, cyber security, and IT security. It defines key concepts like confidentiality, integrity, and availability. It also defines common security threats like unauthorized access, hackers, vulnerabilities, and attacks. It discusses security measures like antivirus software, firewalls, and provides examples of computer crimes and viruses.
This chapter provides an overview of computer networks, including different network types, topologies, protocols, and hardware components. It discusses how networks connect various devices to share resources and information. Local area networks (LANs) connect devices within a single location, while wide area networks (WANs) connect multiple LANs across large geographical areas. Network types include wireless LANs, personal area networks, metropolitan area networks, and peer-to-peer networks. The chapter also covers benefits of networking such as reduced costs, increased communication and collaboration capabilities, centralized administration and backup, and avoidance of file duplication.
This document discusses basic security concepts, including definitions of security, assets, and the principle of easiest penetration. It describes three classifications of protection: prevention, detection, and reaction. Examples are given for physical and cyber security. The goals of security are defined as integrity, confidentiality, and availability. Common security threats are interruption, interception, modification, and fabrication. Vulnerabilities in computing systems can occur in data, software, hardware, and exposed assets. Methods of defense include encryption, software/hardware controls, policies, and physical controls. System access control and data access control are important methods for making systems secure using identification, authentication, and access authorization.
The document discusses various topics related to computer security including threats, attacks, and security mechanisms. It defines key terms like intruder, threat, attack, and different types of security breaches. It describes common attack methods like masquerading, replay attacks, and man-in-the-middle attacks. It also discusses security mechanisms at the physical, human, operating system, and network levels and techniques for user authentication.
This document discusses data security and integrity. It covers various threats to data such as system crashes, corruption, hacking, and human errors. It recommends measures to secure data like backups, antivirus software, passwords, access controls, and encryption. The importance of regular backups, firewalls, and strong passwords is emphasized to prevent data loss and unauthorized access. Biometric security methods like fingerprints and voice recognition are also introduced.
Computer and network security helps protect data and equipment from internal and external threats. Internal threats come from inside an organization from users and employees, while external threats come from outside the organization from unauthorized users. Security threats can physically damage equipment or steal and corrupt data. Malware like viruses, worms, Trojans, and spyware are common security threats that can be installed without user knowledge and harm computers. Organizations implement security policies, passwords, and other measures to protect against these threats.
The operating system plays a key role in system security as vulnerabilities at the OS level expose the entire system. System administrators must provide defenses against attacks by keeping OSs updated. Survivable systems resist attacks, recognize and recover from attacks, and adapt defenses. Regular backups stored off-site are crucial for disaster recovery. Intentional attacks aim to gain unauthorized access through techniques like denial of service attacks, viruses, and blended threats combining multiple malicious payloads. Comprehensive protection requires antivirus software, firewalls, access controls, encryption, and careful password management with strong, unique, and regularly changed passwords.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
