This chapter discusses network security concepts like types of attacks, mitigation techniques, and access control lists. Standard access lists filter based on source IP addresses while extended lists can filter on additional attributes like destination address, protocol, and port numbers. Access lists are applied to router interfaces to permit or deny traffic and help implement security policies. The document provides examples of how to configure standard and extended access lists on Cisco routers to control network access.
Step by Step guide to set up a simple network in Packet TracerSorath Asnani
This document shows the detailed Steps to set up a simple network inside Packet Tracer. You will get familiarity with the software after following the Steps.
Network Address Translation (NAT) is a way to map an entire network (or networks) to a single IP address.
NAT is necessary when the number of IP addresses assigned to you by your Internet Service Provider is less than the total number of computers that you wish to provide Internet access for.

CODE BLUE 2014 : Physical [In]Security: It’s not ALL about Cyber by Inbar RazCODE BLUE
Today's threat landscape is all about Cyber. We have cyber threats, cyber security, cyber warfare, cyber intelligence, cyber espionage... Cyber is a synonym for the Internet, but sometimes, it's not -all- about the internet. Focusing defences on the Internet front leads to some wrong assumptions and the overlooking of much simpler, yet just-as-dangerous attack vectors.
Module 10: Configuring and Troubleshooting Network File and Print Services
File and print services are some of the most commonly implemented network services for end users. Unlike infrastructure services like DNS, file and print services are highly visible to the end users. In this module, you will learn how to configure and troubleshoot file and print services to provide high quality service to end users. In addition, you will see how both EFS and BitLocker can be used to increase the security of files that are located in file shares.

SEC450 ACL Tutorial
This document highlights the most important concepts on Access Control List (ACL) that
you need to learn in order to configure ACL in CLI. This tutorial does not intend by any
mean to cover all ACL applications, but only those scenarios used in then SEC450
iLabs.
Introduction to Access Control List
A host-based firewall essentially works closing and/or opening ports in a
computer. The engine behind firewalls is built with Access Control Lists (ACL).
Network-based firewalls are implemented in device-specific appliances and
routers. Basically, firewalls in routers filter packets through interfaces to permit
or deny them.
Ports are layer-4 address specified in TCP/IP protocol suit that identify
networking processes running in clients and servers.
ACLs are configured using shell-specific commands. In Cisco IOS, CLI
commands access-list and access-group are used to create and apply ACL on
an interface.
ACL can be named by number ID or a name. Naming ACL is useful to identify
ACL’s purpose.
ACL are classified in Standard ACL, and Extended ACL.
Standard ACL’s number IDs are assigned from 1 to 99. Extended ACL’s number
IDs are from 100 to 199.
Standard ACL only uses source IP address in an IP packet to filter through an
interface. Hence, standard ACL denies or permits all packets (IP) with the same
source IP regardless upper protocols, destination IP address, etc. Example 1:
Router(config)#access-list 8 deny host 172.12.3.5
Extended ACL does filtering packets based on protocol, source IP address,
source port number, destination IP address and destination port number.
Example 2: Router(config)#access-list 102 deny tcp host 10.0.3.2 host
2
172.129.4.1 Deny tcp packets with source IP address 10.0.3.2 and destination IP
address 172.129.4.1.
Since, Standard ACLs only have source IP address; the rule is to apply them in
an interface as closer as possible to the concerning destination network.
For the contrary, the rule for Extended ACLs is to apply them in an interface as
closer as possible to the source IP address.
Use Extended ACL in all iLabs as they are more granular on packets to filter.
Create Extended ACL in global configuration
You can use access-list command options lt, gt, eq, neq, range (less than,
greater than, equal, not equal, range of ports) to do operation with port numbers.
Example 3: access-list 102 deny tcp any host 11.23.45.7 gt 20 denies all
packets with any source IP address to destination IP address 11.23.45.7 and
destination tcp port greater than 20.
Example 4: access-list 107 permit udp any any permits all packets with udp
protocol with any source IP address to any destination IP address.
Extended ACL can do packet filtering based on source port number and
destination port number.
Extended ACL Syntax can be as follows:
access-list <#,name> <protocol> ...

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
