网络安全是一场持久战, but there are significant steps you can take to keep your IT defenses strong and effective, one of which is to increase your knowledge of 安全 threats. Here are five common ways your business systems can be infiltrated.
1. You are tricked into installing malicious software
There are countless ways you can be tricked into downloading and installing malware. One is by downloading software from torrent websites. When you visit these sites, you are told to download software in order for the site to load properly. Once downloaded, the malware that came with the software infects your system. In other cases, hackers send emails with a malware-infected attachment.
Luckily, there are steps you can take to avoid accidentally installing malware:
- 不要从不受信任的来源下载文件. If a website is asking you to download something, make sure it’s reputable and reliable. 还要仔细检查网站的URL, as hackers can spoof legitimate websites and use similar but slightly altered URLs, 比如“www”.g00gle.Com”而不是“www”.谷歌.com.” If you are unsure, it’s best to avoid downloading and installing the software.
- Always look at the name of the file before downloading. A lot of malware is often deliberately given names similar to those of legitimate files, with only a slight spelling mistake or some unusual wording. If you are unsure about the file, then don’t download it. If you know the sender, you may contact them to verify the file’s authenticity.
- 总是在安装文件之前扫描它. Use your antivirus scanner to check downloaded files before opening them.
- Stay away from sites with torrents, adult content, or those that stream pirated videos. These sites often contain malware, so avoid them altogether.
2. 黑客获得管理员权限
Many users are 登录to their computers as admins. Being an administrator allows you to 改变设置, install programs, and manage other accounts. The problem with this is that if a hacker manages to access your computer with you as the admin, 他们可以完全访问你的电脑. This means they can install other malicious software, 改变设置, 甚至完全劫持机器.
Even worse is if a hacker gains access to a computer used to manage the overall IT network. Should this happen, they can control the entire network and do as they please.
为了避免这些不幸的情况, limit the administrator role only to users who need to install applications or 改变设置 on their computers. Installing antivirus software and keeping them up to date, 以及进行常规扫描, will also help reduce the chances of being infected.
3. 有人侵入了你的电脑
Your system can also get infected with malware or your data can get stolen because someone physically accessed your systems.
Let’s say you leave your computer unlocked when you go out for lunch. Someone can just walk up to it and plug in a malware-infected USB drive, 哪些会感染你的系统. They can also manually reset the password, thereby locking you out.
An easy way to defend against this is to secure your computer with a password. You should also lock, turn off, or log off from your computer whenever you step away from it. You can also disable drives like CD/DVD and connections like USB if you don’t use them. Doing so will limit the chances of anyone using these removable media to infect your computer or steal data from it.
4. Someone from within the company infects the system
A disgruntled employee can compromise your IT systems. They can do so much damage such as deleting essential data or introducing highly destructive malware.
最有效的预防方法, 除了确保你的员工快乐, 是限制对系统的访问. For example, you may find that people in marketing have access to finance files or even admin panels. Revoke unnecessary access rights and ensure that employees only have access to the files they need.
5. 您的密码被泄露
Passwords are typically the main verification method businesses use to access their accounts and systems. The issue with this is that many people have weak passwords that are easy to crack. 更糟糕的是, many people even use the same password for multiple accounts, 这可能会导致大规模的漏洞.
It is therefore important to use strong and different passwords for your accounts. It’s best to also utilize multifactor authentication, which requires users to present more than one way to verify their identity such as a password plus a fingerprint or a one-time code.
