This document summarizes security issues in PHP applications. It discusses three lesser known vulnerabilities: 1) PHP path normalization can be bypassed on Windows through special characters like double dots and pipes, allowing access to files outside the web root. 2) Double-byte character sets can be escaped to bypass input validation in SQL injection and XSS attacks. 3) Variables in double quotes undergo string evaluation, which can enable code injection through functions like phpinfo(). The document provides solutions like sanitizing special characters, proper UTF-8 encoding, and avoiding eval-like functions.

OWASP Top 10 2021 – Overview and What's New.
OWASP Top 10 is the most successful OWASP Project
It shows ten most critical web application security flaws.
Read the presentation and you will learn each OWASP Top 10 category and recommendations on how to prevent it.
The document discusses a presentation by Imran Bashir on advanced design and scaling of Cisco Identity Services Engine (ISE) networks, including an overview of the speaker's background, the session agenda covering topics such as sizing deployments, high availability, monitoring, and services scaling, and a diagram of the ISE deployment options including standalone, multi-node, and high availability designs.
The document discusses Access Control Lists (ACLs), which are lists of permit or deny rules that control what traffic can enter or leave a router's interface. There are standard ACLs, which filter traffic based only on the source IP address, and extended ACLs, which can filter traffic based on additional attributes like destination address, protocol, and port numbers. ACL rules are evaluated sequentially, with an implicit "deny all" rule at the end, so ACLs should be placed strategically to filter traffic close to either its source or destination.

This document provides an overview of the OWASP Top 10 Risk Rating Methodology. It explains how risks are rated based on four factors: threat agent, attack vector, technical impact, and business impact. Each factor is given a rating of 1-3 (easy to difficult) and these ratings are multiplied together to calculate an overall weighted risk rating. An example of how this methodology would be applied to an SQL injection vulnerability is also provided.
Privileged access refers to system permissions that allow overriding of controls and accessing sensitive information. Privileged accounts have special permissions that can significantly impact an organization's systems and databases. Proper management of privileged access is needed, including monitoring passwords, logging activity, and ensuring access is traceable to individual users. This is the goal of Privileged Access Management (PAM).
0wn-premises: Bypassing Microsoft Defender for IdentityNikhil Mittal
?
This document discusses bypassing alerts from Microsoft Defender for Identity (MDI). It begins with an introduction to MDI and the types of alerts it generates. It then explores techniques for bypassing alerts during different phases of an attack like reconnaissance, credential compromise, and lateral movement. These include using alternative tools, limiting interactions with domain controllers, and complying with Kerberos policies. The document also notes techniques like silver tickets that are not detected by MDI. It concludes by acknowledging limitations of only testing alerts and not coupled defenses.
The document discusses how F5 networks provides comprehensive web application security through its full-proxy architecture and web application firewall that protects against common attacks like SQL injection, cross-site scripting, and brute force attacks. It also explains how the F5 solution uses a positive security model to allow wanted transactions while denying everything else, providing implicit security against both known and unknown attacks.

Anti bot – identify the attack agent as bot and apply prevention policy on it
Source IP – identify the attack agent origin from which the attack is originating and apply prevention policy on it
Signature – identify a pattern of the exploit or the attack agent in the payload and apply prevention policy on it
This document discusses various techniques for Linux privilege escalation. It begins by defining privilege escalation and explaining the process. It then covers common escalation methods like exploiting kernel vulnerabilities, accessing programs running as root, using weak or default passwords, leveraging insider services, abusing SUID configurations, taking advantage of sudo rights, manipulating world writable files run as root, path manipulation, cron jobs, and keylogging. It provides examples and commands to help identify these opportunities on a target system.
The document discusses the differences between traditional penetration testing and "Red Team" services. Red Team services involve simulating long-term advanced persistent threats and coordinating with blue teams to improve defenses. This goes beyond typical penetration tests by including physical, social, and threat simulation methods over an extended period. The document provides examples of Red Team techniques and tools used, such as open source intelligence gathering, phishing emails, and living off the land post-exploitation tactics.
This document discusses advanced threat protection and FortiSandbox. It notes that prevention techniques sometimes fail, so detection and response tools are needed to reduce the time it takes to find, investigate, and remediate incidents. Sandboxing is introduced as an effective technique that runs suspicious objects in a contained virtual environment to analyze behavior and uncover threats. FortiSandbox is highlighted as a solution that integrates with FortiGate and other Fortinet products to provide detection, analysis, and sharing of threat intelligence across the network to improve security.
sqlmap is an open source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers.
This document discusses F5 mitigations for dealing with attacks on web servers. It describes several techniques for detecting and preventing bot attacks including:
1. Client-side integrity defense (CSID) which uses JavaScript challenges to verify clients are browsers before serving content.
2. CAPTCHA challenges which require humans to solve puzzles to prove they are not bots before accessing sites.
3. Request blocking which limits request rates from suspected bot sources through rate limiting or blocking offending IP addresses.
F5 provides both on-premises and cloud-based DDoS protection solutions. Their hybrid approach mitigates attacks at the network, transport, and application layers using hardware-accelerated detection and filtering of over 110 DDoS vector types. Key capabilities include comprehensive L3-L7 protection, multi-terabit cloud scrubbing, and integration of network firewall and web application firewall technologies to strengthen security and ensure application availability even during large DDoS attacks.
This document discusses cyber deception techniques for detecting cyber attacks. It introduces concepts like using decoys and breadcrumbs like credential lures and file lures to detect attackers moving laterally in a network. It also discusses the MITRE attack framework and deception placement using tactics like decoys and breadcrumbs to detect attackers at each phase of an intrusion kill chain. The document is intended to provide proposal information for customers on cyber deception implementation.
