ファイアウォールのログへのルーターの侵入

Question

ルーターがインターネットに接続するたびに、ルーターのファイアウォールログへの侵入に関する警告が表示されます。それが何を意味するのか説明してもらえますか？それは実際に誰かが私のルーターをハッキングしているのですか、それともその接続がルーターによって切断されているのですか？

例えば.

Mar 11 14:15:11 kernel warning kernel: [fwlog] Intrusion -> SRC=85.102.133.241 DST=109.78.126.234

これが私のルーターファイアウォールの完全なログです

オンライン中にいつでもポートスキャンの対象となるのは完全に正常です。これは不幸な真実です。それでも、脆弱なサービスがインターネットに公開されていない限り、これによるリスクはありません。

あなたが見ているのは単なる情報メッセージです。害はなく、ハッキングも試みられていません。

侵入ではなく、誰かがルーターを外部からスキャンして、開いているポートを見つけようとしたことを意味します。私はそれについてあまり心配しません:)

通常、ルーターでは、ネットワークへのポート（より良いWordがないため、「ゲートウェイ」と考えてください）は閉じられています。これらのポートは、さまざまな理由（独自のWebサイトのホスティングなど）で手動で開くことができます。

「ハッカー」は、これらの開いているポートをスキャンして、PCへのルートを見つけようとします。これらを手動で開いていない場合は、完全に問題ないはずです。よくわからない場合は、独自のポートスキャンを実行できますここそして何か開いているかどうかを自分で確認してください:)
