  1. 1. Generic Encrypted Traffic Identification using Network Grammar : A Case Study in Passive OS Fingerprinting

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Lukas Rajala; Kevin Scott; [2022]
    Nyckelord :Passive OS Fingerprinting; Encrypted Traffic Identification; Automated Traffic Analysis; Machine Learning; Supervised Learning; Networks; Packet Classification; Security and Privacy;

    Sammanfattning : The increase in cybercrime and cyber-warfare has spurred the cat-and-mouse game of finding and attacking vulnerable devices on government or private company networks. The devices attacked are often forgotten computers that run operating systems with known exploits. LÄS MER

  3. 2. The Everyday Internet, a Minefield in Disguise : Characterization of different types of domains including malicious and popularity

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Linn Petersson; Rebecka Lindkvist; [2022]
    Nyckelord :characterisation; malicious; domains; vulnerabilities; cipher suites; TLS; protocols; security; certificates;

    Sammanfattning : Today, security has become a growing concern for all internet users, where technology is developing faster than its security is implemented, which leads to insecure domains. In this thesis, we look at the reality of today’s domains and research if some categories of domains are safer than others and the reason behind it. LÄS MER

  4. 3. Characterization of cipher suite selection, downgrading, and other weaknesses observed in the wild

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Edvin Kjell; Sebastian Frisenfelt; [2021]
    Nyckelord :TLS; HTTPS; HSTS; cipher suites; vulnerabilities;

    Sammanfattning : The importance of security on the web is growing every day. How domains handle and prioritize their level of security is varying. Tradeoffs between security and convenience have to be made to uphold a website's public image. This thesis uses a subset of domains from the Alexa Top 1M list. LÄS MER

  5. 4. TLS Decryption in passive monitoring system with server private key

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Emil Käck; [2021]
    Nyckelord :TLS; Decryption; Passive monitoring; Server private key;

    Sammanfattning : Many network operators need to be able to ensure that customers get the level of service they pay for. To avoid bandwidth and server performance bottlenecks, and easily troubleshoot network problems, the network providers need to be able to see what payload data is sent. LÄS MER

  7. 5. Security-performance tradeoffs in HTTPS implementations of browsers

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Erica Weistrand; Sophie Ryrberg; [2020]
    Nyckelord :;

    Sammanfattning : Different browsers manage security in different ways when communicating with web servers. Many of these differences are due to browsers making security-performance tradeoffs in the battle to be the most popular browser. This thesis characterize and analyze how browsers manage security in the implementation of HTTPS. LÄS MER
