Do NOT use the wifi that comes with 5G modem or modem with WIFI router as the traffic flow will NOT be protected by Garland.

不要使用 5G 调解器或调解器有无线网络功能的无线网络，因为其无线网络不受「茼蒿」的保护。

FAQ

When will the rules are updated?

24/7

Between 0600 and 0630 hours every day, Garland will do the housekeeping and updating. The defending work of Garland may be interrupted during this period.

non 24/7

Garland can be turned off and it is not required to operate 24/7. The update will be carried out within half an hour when the Garland is booting up. It is advised NOT to turn off the Garland between 0600 and 0630 hours as it will do the update automatically. If you do so, you may break the Garland. Meanwhile, if you turn off the Garland within half an hour of the booting up, you may also break the system too.

How many detecting / blocking rules in Garland?

There are over 47,000 rules in Garland and they are all free of charge. The number of rules are increasing.

Do you recommend to access Garland via SSH in internet?

For security purpose, it is NOT recommended to connect Garland via SSH in internet. However, you may connect Garland via SSH in intranet. The username and password are “garland”. The IP address of the garland is 192.168.x.200, e.g. 192.168.0.200.

Can Garland decrypt the SSL/TLS traffic?

Garland cannot decrypt the SSL/TLS traffic well. However, it can handle a limited SSL/TLS traffic flow. Therefore, it is not ideal for using it as Web Application Firewall (WAF). For example, Garland can detect and drop self signed SSL/TLS certificate traffic and etc.

Do I also need anti-virus on my computer or laptop?

Yes, anti-virus is required. You are also advised to install the following add-ons or extensions for your browser such as Firefox or Chrome in order to increase the security for surfing the internet.

常问问题

何时会更新防御入侵系统的规则？

全日运作

每日的凌晨 0600 至 0630 时更新和维护，其间有可能对防御入侵系统的运作有些少影响。

非全日运作

每当启动后的半小时内其会自行更新维护，所以不要在其间或在 0600 至 0630 时其间内关闭防御入侵系统，因为有可能会损坏防御入侵系统。

防御入侵系统内有多少条规则？

所有规则都是免费的，已经超过 4 万 7 千多条，而且亦每日在增加中。

是否建议在互联网中利用 SSH 接驳防御入侵系统？

不建议，但可以在内网连接。其用户名称和密码都是 “garland”。至于网址是 192.168.x.200，例如 192.168.0.200。

防御入侵系统是否能够解密所有加密的连接？

不能。但她能够识别及阻挡自签 SSL/TLS 证书的流量。

我仍是否需要在电脑上安装防毒软件？

需要。除此之外，我更建议在「火狐」或 Chrome 浏览器安装以下附加组件，使得上网时更安全。

KNOWN ISSUES

Since there is no Real-Time-Clock battery in the device, you are required to reboot the device (the FIRST boot of the burning SD Card) after half an hour in order to get the current local time.

已知问题

因为防御入侵系统没有时钟电池，所以在烧录后第一次开机时，应在半小时后重启一次就可以更正时钟了。
