apt-get update 和
apt-get upgrade 是否提供了足够"安全" 的测量。
I'm currently using a hosted VPS on linode, I was wondering if a daily
apt-get update and
apt-get upgrade is providing a 'secure' enough measurement.
Daily updates will make sure that your software is updated and potentially close vulnerabilities there, but as JFW commented, you should take time and update the firewall/IPTables to close off any unnecessary ports and you should also disable any services you're not using.
