When your computer is accessible through an internet connection or Wi-Fi network, it is susceptible to attack. However, you can restrict outside access to your computer—and the information on it—with a firewall.
What do firewalls do?
Firewalls provide protection against outside attackers by shielding your computer or network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network via the internet. Firewalls can be configured to block data from certain locations (i.e., computer network addresses), applications, or ports while allowing relevant and necessary data through.
What type of firewall is best?
Categories of firewalls include hardware and software. While both have advantages and disadvantages, the decision to use a firewall is more important than deciding which type you use.
Most commercially available firewall products, both hardware and software based, come pre-configured and ready to use. Since each firewall is different, you will need to read and understand the documentation that comes with it to determine whether the default firewall settings are sufficient for your needs. This is particularly concerning because the “default” configuration is typically less restrictive, which could make your firewall more susceptible to compromise. Alerts about current malicious activity sometimes include information about restrictions you can implement through your firewall.
Though properly configured firewalls may effectively block some attacks, do not be lulled into a false sense of security. Firewalls do not guarantee that your computer will not be attacked. Firewalls primarily help protect against malicious traffic, not against malicious programs (i.e., malware), and may not protect you if you accidentally install or run malware on your computer. However, using a firewall in conjunction with other protective measures (e.g., anti-virus software and safe computing practices) will strengthen your resistance to attacks.

What is a social engineering attack?
In a social engineering attack, an attacker uses human interaction (social skills) to obtain or compromise information about an organization or its computer systems. An attacker may seem unassuming and respectable, possibly claiming to be a new employee, repair person, or researcher and even offering credentials to support that identity. However, by asking questions, he or she may be able to piece together enough information to infiltrate an organization's network. If an attacker is not able to gather enough information from one source, he or she may contact another source within the same organization and rely on the information from the first source to add to his or her credibility.
What is a phishing attack?
Phishing is a form of social engineering. Phishing attacks use email or malicious websites to solicit personal information by posing as a trustworthy organization. For example, an attacker may send email seemingly from a reputable credit card company or financial institution that requests account information, often suggesting that there is a problem. When users respond with the requested information, attackers can use it to gain access to the accounts.
Phishing attacks may also appear to come from other types of organizations, such as charities. Attackers often take advantage of current events and certain times of the year, such as

How to Protect your Office, Company or Organization
In recent months several of our clients have received email requests to wire transfer funds. This confidence scheme is highly targeted sending the fake wire transfer emails to employees working in the finance department of a company.
How it works
This con uses sophisticated social engineering to convince specific executives and other individuals with access to their company's accounts to initiate a wire transfer of large sums of money.
In this attack, the scammer not only knows the target's name and email address, but also the name and email address of someone else in the company whom the target might trust. The scammers have registered email domains that are very similar to the recipients' (for example: xyzwigdets.com instead of xyzwidgets.com) and send the email from the fake domain.
So, instead of coming from firstname.lastname@example.org, the email comes from email@example.com. The scammers are betting that some people won't notice the slight difference in spelling and thus won't suspect anything.
A Slow Con - No Dollar Amount at First
This is an old-school trick we don't often see in email scams. The scammer cons the victim slowly, first gaining their trust and then moving in for the kill.
In some of the emails, the first message is not only ordinary, it doesn't even request a specific amount of money. It merely asks to initiate a wire transfer today. The recipient, thinking it's coming from a co-worker who might ask for a wire transfer, replies to the scammer, who then engages in a brief email exchange, eventually asking for a specific amount. The scammer even confirms the money went through, probably to prevent the victim from becoming suspicious and reversing the transfer.
Why doesn't our Spam filter catch these?
This is a different type of threat. With its low-volume (only a handful of emails out of millions) and targeting of specific people, this dangerous campaign has few of the typical markers of spam.
Why is this scam so successful?
The people perpetrating these frauds frequently research employees’ responsibilities so they know who to target, and often gather information to try to make the wire transfer request as believable as possible. For example, they may research the executive’s schedule using public information or by making inquiries of the executive’s assistant with the goal of sending the fraudulent emails when the executive is out of town and cannot be easily reached for verification.
Although some of the fraudulent requests are for millions of dollars, they can just as often be for smaller amounts. Since many companies have stricter controls (like dual approvals) for amounts over a certain dollar threshold, the scammers often submit requests for lower amounts hoping the looser controls will raise the success rate of their scam. If the scammer is successful in a preliminary request, they may continue to submit additional requests until the scam is detected.
How to Protect Yourself and Your Company
Implement a Strong Policy: Security and Fraud Prevention begins with a solid set of policies and procedures. A company policy should include confirmation on any wire transfers. Train everyone at your company based on your policy. Keep your staff up to date on the latest threats.
