Exercise 1 - Installing and Configuring Antivirus Software
In this exercise, you will learn the following using Windows Server 2008 R2:
- Installing and configuring Antivirus Software
- Creating a Pointer Record
- Creating a Sender Policy Framework Record
Antivirus software is a program that is used to prevent any malicious software (malware) from disrupting your computer operations, destroying the data on your computer, or gaining access to private and sensitive data stored on the computer. Malware can be transferred to your computer in the form of code, scripts, active content, or another program. The antivirus program scans any files you download or copy to your computer before saving them on the computer. You can also configure the antivirus program to scan your computer periodically or scan on-demand to remove any malware that would have entered your computer through some e-mail or website.
Exercise 2 - Creating Pointer Records
Domain Name System (DNS) is a TCP/IP network service that resolves a computer’s fully qualified domain name (FQDN) to its numerical Internet Protocol (IP) address and vice-versa. FQDNs and IP addresses are added into DNS zone and these entries are called as resource records (RRs). There are many types of resource records that can be created in DNS and one of these is pointer record.
A Pointer record or PTR record is a reverse DNS record that associated an IP address with its canonical name or fully qualified domain name. The name of the PTR record is formed using the four IP octets of the IP address followed by IN-ADDR.ARPA.
In this task, you will learn how to create a Pointer Record.
Exercise 3 - Creating Sender Policy Framework Records
Sender Policy Framework records are used to prevent email spoofing. Spoofing means impersonating emails or forging emails such that the emails appear as if they have been sent from another address. Using Sender Policy Framework records, you can specify all the IP addresses that you would use to send emails in a single TXT record. This record tells the receiving server to allow only those outbund servers you have listed in the record.
In this task, you will create a sender policy framework record.
