This document configures a router with the hostname R1, including enabling secret passwords, setting interfaces for connections to other routers and VLANs for various LANs, configuring OSPF routing with passive interfaces, and writing the configuration.
A single change to a network device can have far reaching effects on your business. It can create security holes for cyber criminals, impact your regulatory audit, and even cause costly outages that can bring your business to a standstill!
In this technical webinar, Anner Kushnir, VP Technology at AlgoSec, will present several examples of common misconfigurations; including a basic device change, business application connectivity changes, and data center migrations. The webinar will cover best practices and demonstrate specific techniques to help you understand and avoid misconfigurations, and ultimately protect your business from attack.
Join the webinar to discover how to:
•Understand and map your enterprise infrastructure topology before you make a change
•Proactively assess the impact of a change to ensure it does not break connectivity, affect compliance or create a security hole
•Avoid common mistakes when making changes to your network security devices
•Understand business requirements from the network security perspective
Cessation of Misconfigurations: Common Network Misconfiguration Risks & How t...AlgoSec
Misconfigurations aren’t simply inconvenient mistakes but serious security threats. According to Gartner, 99% of all firewall breaches will be caused by misconfigurations by 2020 and misconfigurations made OWASP’s list of Top 10 most critical web application security risks.
A single change to a network device can have far-reaching effects on your business and create security holes for cybercriminals, impact your audits, and cause costly outages that bring your business to a standstill.
In this webinar, Avivi Siman-Tov, AlgoSec’s Director of Product, will show examples of common misconfigurations, including device changes, business application connectivity changes, and data center migrations. He will also reveal specific techniques to help you avoid them.
